On both social media I still use, I followed bunch of indie ttrpg devs. I had to unfollow the ones on tumblr because they don't talk about anything but how much they hate D&D, up to including writing weird headcanons about people who help popularize it (I actually seen someone on tumblr claim Brenann Lee Mulligan must HATE D&D because only dumb people could like it and is only pretending to like it for clout) or bich about how D&D fans only want to play D&D and get mad when you tell them they're complaining about a small minority.
meanwhile indie ttrpg devs on Bluesky constantly promote their work and inform of sales of their products. I found many cool games through bluesky, meanwhile nove through tumblr.
Some people just love to bitch, especially if that's all they do. James Wallis said (IIRC) "Game designs aren't tools, but some game designers are".
