Sounds like ongoing ticktockification to me. I think from the perspective of a social media company, the ideal UI would not allow the user any kind of agency in what content is shown and would be 100% driven by the algorithm. Of course users don't want that, so what we have in practice is social media companies testing how close they can get to their ideal without upsetting too many users.
