I'm tired of people arguing that the sum of the people in the platform does not equal its culture. Facebook and other social networks clearly benefit from having influencers in their platform, and they make the platform orbit around it.

People who use facebook are not responsible for old people posting what they want. But also, Facebook earns profit from that kind of behavior, so it makes its algorithms circle around it.

It's like saying Instagram isn't responsible for all the influencers and the 'vibe' it has. It is responsible for it and you don't make the platform your own, especially not with the Big players.

Even Mastodon, where you can set up your own instance, has its culture, even if it is richer (culturally) than Instagram or Facebook.

No, each person does not make the platform their own or make out of it what they will. Only a masochist would stay on Facebook preaching their own culture while they have other options that fit better.

Your argument fails.

Also, on another note, I'm tired of Carl Sagan's atheists using Darwinism as basis for lack of a God, and I'm not a christian or muslim. That's just reason to silence people who don't want to take "scientific" argument at face value. True science is debatable and built upon healthy discussion. Not something you toss at other people to make them seem dumb or preach like a religion.
