I think the major issue is, people still have the option of those older forms of feeds, people just don't like them.
New social media competitors (ie Tiktok) have won users by having even more powerful algorithms rather than other options.
Of course, but the users can’t be trusted to stay away from something designed to addict them. Only real solution is regulation, although the how is still a big question mark.
How? The 2 feeds on my IG account: "posts" and "reels" show content of people that I do not follow.
