Just stop paying attention to grifters. Seriously. Stop validating them by letting the pre-programmed bullshit they say have any weight in your head whatsoever. They say the same shit every single time, and thus it doesn't mean anything. They, and the chuds who buy into them, are literally not worth giving a speck of merit.
Ignore them.
I'm a little confused why artists are nay-saying the swap from twitter to bluesky so hard. I mean I understand that twitter has a much larger userbase, but I really don't believe that it would be that difficult to establish bluesky as the place to go to see updates from one's favorite artists. After all, not all that long ago almost every artist was using tumblr until that whole snafu happened, and it's not like tumblr had a bigger userbase than twitter at that point, it was just that tumblr was the place to go to see new art drops. So why not just... make a new place again? Or at least give it a shot before immediately giving up on the idea.
