I think it's more than this, at least for FB. FB has always strived to manipulate feeds. Before it left chronological feeds just over a decade ago, they were busted for doing psychological experiments by manipulating user feeds without user consent. Of course that 'consent' came in the form of the ToS, which gradually evolved over so many years. Needless to say, FB has pissed off tons of users. Even through Covid and the election, a large chunk of people left and they left because they do'nt want the manipulation. Unfortunately, the newer generation is growing up with this as the new normal.
