> The personalisation of the adverts is, at least in my case, pretty terrible — FB and Twitter categorised me as being interested in sports I've never watched, languages I've not learned, and politics of countries I've never lived in.

Part of the reason for the push for opaquely-personalised ads could also be because advertising platforms can effectively defraud their advertisers by serving their ads to people who have no interest in them, which would be impossible in a world where people explicitly choose which types/categories of ads they're interested in.

Why would a platform ever do this intentionally? This will just result in lower CPM and advertisers pulling out.

It's possible. You can still make an ad model to give people the worst ads and ignore their preferences.
