I think that regular users don't really care, why would anyone obsess about tracking down which account liked which post? the only people who get into that sort of thing, are people who likely manipulate with multiple accounts themselves. and they don't wanna be traceable and that's why they're afraid of this feature.
they were always lying, they were always gonna replace people with AI. they just didn't want you to know back then, that's all this means. they still needed u to train their model...
