As already mentioned, the matchmaking will not put you on community servers, and its existence has pretty much killed the majority of the community server scene. The game has more players than ever but less community servers than ever and most server mods that used to be very popular have been abandoned as a result.
I mean isnt that an indictment against the system by the community at large? People favor quick, normalized matchmaking. Having the option is amazing, but I dont think the general population really wants that, even if they would say they want the choice. Hard to justify the effort for the company then IMO.
Yes, most people are lazy and will always pick the most obvious and convenient option. No, that doesn't mean that the most obvious and convenient option is better.
The general population doesn't really "want" anything, they're satisfied with whatever they're fed and rarely think about it at all. Back in the server browser days you didn't hear constant complaints from people who wanted matchmaking instead, the switch to matchmaking happened because developers wanted to optimize engagement and increase their control over the game experience so they could monetize it more effectively, that's it.
