actual reason that pugs are dead is that people are super selective about who they play the game with.
everytime I invite someone to play a pug or a dmix they ask who is in it, and if theres a player or two they don't vibe with they don't join.
so we are stuck in this divided hell of a bunch of different discord dmix servers etc.
essentially people don't play for the love of the game, they just want to play with people they like, and because the scene isn't big enough, we cannot maintain a public pug site.
not much to be done about that, just get used to not playing much tf2 outside of your happy little circjelerk, or your team
