@fluffy While it may be counter culture to blame, or any other number of factors. Who or what is to blame is less of concern to me than what is or is not. The truth is, the qualities I describe are inherent to twitter regardless of blame, and are far less evident in the fediverse or Facebook. Reasons to avoid the platform even if the company isnt to blame for the effect.
Yea people being "fake", in the sense of trying to put on a political front (usually called being professional) is something you can see in any context. But it is far worse in twitter than other mediums. Its a matter of degrees not absolutes.
As for identity. You can pick any identity on twitter you wish, just as you can here. Neither platform requires you to identify yourself.
