I always wondered about this.... in the beginning of instagram, i would follow maybe 30, 40 people, open it 2-3 times per day, and every time there would be 3-5 new photos of random stuff taken by those people (lunch/dinner plates, views from the window, beer glass on the bar, whatever).

Years later, i would follow 200 people, and i would open instagram once per day and all i'd see were random peoples photos and videos (reels? i don't know what they're called anymore), some from international influences, some like stuff that can be found on 9gag, etc. Even if i switched to "following", there would maybe be 1 photo made by a person I actually followed.

Did the algorithm make people stop posting their personal daily stuff? Did people change?

I guess it's even worse now, but i've uninstalled it a few years ago.
