i think they could if they started with "show users content they like" instead of "keep users staring at the app for as long as possible". both result in more engagement and more ad dollars, but optimizing for the latter becomes a race to the bottom with increasingly extreme, polarizing, emotion-inducing content.
the blatant algorithm manipulation around elections and politics is just the icing on the cake. sure, china is probably doing this too, but they're either being more subtle or playing a longer game. meta et al may have come out ahead for a few quarters but what's that worth if user count is declining long term?
