Interesting, I wonder if the 2 facts are somehow related, I don’t know what their stance was on the free software side of things, though I may have some emails saved from GitHub notifications that say something, I’ll look for those.

Edit: I don’t have any on the topic of F-droid inclusion, unfortunately, just one about language support

We are a small team and are not looking for people who can contribute to the project

This bogus argument is always big no no for me, clearly if they’d just been a small team they would not only accept, but enjoy whatever kind of contribution they can get from external people.
They just don’t want to deal with the community and do whatever they want, I’m guessing.

they don’t want our help, their loss

Spot on!

Glad to know I wasn’t alone on this, it is a shame really

Honestly if you don’t want to think too much about it, go with Briar, it’s way more battle tested, while Berty seems like it hasn’t seen much adoption since it’s younger, both have a bit of development activity I saw, so I can’t say if one is more or less maintained than the other

As for the actual question of gauging which has the better cryptographical implementation, I don’t know either, beside the most surface level information I know very little.
I believe if you want to look into it, you’ll have to start from their whitepapers

Besides the already mentioned Briar, there’s Berty, can’t speak to its quality since I never used it, but I always found the project neat in and of itself

Besides the files that are easy enough to move over, for app data there really is no other choice than to either haves ones that support their own export/import functionality or if you’re not lucky enough to have eliminated the apps that don’t have it and need their data you can only go back to papa Google and ask to politely get all your stuff for restoration on the new phone.
Takeaways:

1. If you care more about salvaging data than privacy, use a Google account on your phones, otherwise, if you still value privacy but not so much security, root a phone as soon as you get it (not always possible or desirable) so you can use other backup solutions that require root access.
2. Prefer installing apps that have an embedded backup functionality so you can be sure it’s always possible to get the data out regardless of what you did about point 1
3. (Bonus) Ask for said backup functionality to be added to apps you’d like to use with a feature request on the app’s repo when it’s open source, I’ve been doing that for the past year or so and I saw that quite a few have gone and implemented it, love these dudes :)
4. (super extra bonus) Fuck Google for artificially preventing a full backup solution that doesn’t rely on their cloud being involved

They should take you to dinner first

You have quite a bit of background knowledge to know how to do that though, you should give yourself more credit!

What if the Geoguesser players are the AI?

You’re hired!

No, no, I’m hired

I’ve been using LinkedIn with addy.io’s aliases a couple years without issue, I can’t say if that somehow makes your profile less promoted, I can only say that I’ve been receiving a few proposals here and there, don’t have a lot of experience, so I think it’s reasonable I don’t get swamped in them.
To be fair though, the real privacy concern is all the information you have to share about yourself and that can’t be avoided, regardless of the platform, you have to give details about you because that’s the entire reason you would be on such a platform to begin with, to make yourself known.
What you can do is leave out all the details you’re not comfortable sharing publicly and instead wait for recruiters to eventually ask you for those themselves, so you know that it only goes with one party that you have interacted with and can “trust”, rather than the wider internet.

As for the email spam, there are a LOT of bs emails you receive by default from LinkedIn, but you can disable them, it took a while for me to figure out which is which because they have so many settings, but now I managed to have only what I care about, which is pretty much requests for connection and messages.
Also you don’t have to install their mobile app even if they bug you about it, you can get by with the mobile PWA and if you want to do any Easy Apply job applications, you can just temporarily switch to desktop mode

It believe that too, the project just received more backing, it hasn’t been taken over by a random new group

I see, that makes sense

You mean unrestricted battery usage? If so, I don’t exactly understand how it differs from keeping the unifiedpush integration off and relying on the app, does it make it so that it’s only “ready” to be triggered by ntfy when it would otherwise poll the server on its own very frequently (so you end up actually saving some battery)?

Spot on response!
Just a note: in my experience Mercurygram with ntfy is terribly unreliable, with notifications coming in days later, so I personally ended up enabling its background service anyways, it doesn’t look like it’s taking up much battery at least

Yeah that’s also a good solution!

Piped always does, it’s the way it works. Invidious is not always like that, at least if what is said in this issue is still true, it depends on the instance

I feel like most have misunderstood the point of the question, they offer to use newpipe, yt-dlp and the like, but those aren’t private, they just allow you to watch without signing in, just as you could through the official website with maybe uBlock origin, you’re still exposing your IP.
The only fitting suggestion I saw is that of downloading from invidious through yt-dlp, which sounds pretty neat, I had no idea you could when the web frontend is apparently not working

So it’s just a branding thing? That was my understanding already, I thought you meant there were functional differences

Is there an explanation of the differences?

someone compared Chromium and Firefox without any real conclusion

Are we talking about mobile or desktop? Because, as of now, Chromium is still winning on mobile
