That’s a pretty common take. Lots of people don’t want teammates or opponents in their multiplayer games who are still figuring out the basics of play (or in equipment/gear/level-based games, have none).
In games with skill- or level based matchmaking it’s not that bad provided there is enough of an active player base to isolate the newbies to their own pool, but not all games have either of those two things, never mind both.
