You can't really blame this on the people. The centralized platforms offered something that for most people worked a lot better than what was already existing. In the beginning, those corporate platforms were actually quite good so it's only natural that people flocked to it.
It's only after those companies achieved a monopoly in their market, that they started pulling a bait-and-switch and began to enshittify their sites. Network effect makes it so that mass migration to something that's technically better is unlikely. This bait-and-switch is where they stole it from the people.
