I think automatic global matchmaking is a bit of a cursed problem because how people want to play a game is multidimensional beyond just their skill level at the game, it may change from session to session, and some players are incentivized to lie about it.

You can see some attempts to address this with having casual 'unranked' and competitive ranked matchmaking modes, but this still runs into whether casual means 'just fuck around and not even try to play the objective' or 'play the game as a team but not be quite so focused on winning at any cost'.

People who complain about SBMM it because they just want to pubstomp are mostly just whining and want their fun at the expense of 1-11 other players, though. (I recall a conversation on here where someone was saying that the optimum winrate for chess to keep someone engaged is about 80% and did not seem to understand that there was no way to have a group of people playing chess against each other with an average 80% winrate each)
