I'm genuinely curious why? I read a little bit about Cara and sure it sounds nice but what's particularly stopping them from pulling the same move as Meta in the future?
Well, they are run by artists and founded by a pretty famous photographer, so it's more probable that they'll stick to it than, say, a tech billionaire trying to control the world and pump stocks.
That could always change of course, but I'd say they are a safer bet than any company built on harvesting data.
