gollark: That *kind of* exists now, but it's not very good.
gollark: Some company will set headlines for a >$2000 phone, but then more will do it and it'll eventually become normal for ultraflagships or something to cost that much.
gollark: Maybe right-to-repair will become a more mainstream political thing, but it probably won't actually *happen* in most countries, despite definitely doing more for environment wotsits than plastic straw bans and whatnot.
gollark: I mean, I think a decent amount of the money is wasted.
gollark: Targeted adverts, though?
