(the preview fetch is not e2ee afaik)

Technically, it is, but end to end encryption only covers the data between the ends, and not what one of the ends chooses to do with it. If one end of the conversation chooses to log the conversation in an insecure way, the conversation itself might technically be encrypted, but the contents of the conversation can be learned by another. Or if one end simply chooses to forward a message to a new party not part of the original conversation.

The link previews are happening outside of the conversation, and that action can be seen by people like the owner of the website, your ISP, and maybe WhatsApp itself (if configured in that way, not sure if it does).

So end to end isn’t a panacea. You have to understand how it fits into the broader context of security and threat models.

It’s just a type of injury. Injuries themselves don’t give you a right to sue, you have to be injured by someone else doing something wrong.

Can I sue for blindness? Yes, if someone caused my blindness in a way that they’d be liable for. Same with other injuries like broken bones or lost employment or embarrassment or paralysis.

So if someone drives drunk and hits you with their car, paralyzing you and causing loss of enjoyment of life, you can sue them and would have to prove liability (they caused your injury in a way that causes them to have to pay for it) and damages (the amount of money they owe you based on how injured you are). Something like loss of enjoyment of life would be part of the second part of the analysis.

If there were superheros that could violate the laws of thermodynamics at will, I would expect them to at least run the world on limitless clean energy.

It would probably only take a little bit of time to figure out ways to store the energy so that all of society could run without the superheros continuously working shifts and stuff: like maybe they just reheat a molten salt core from time to time, or fill up a high altitude lake with water upstream from some hydro plants.
