Your point about VTTs is exactly why I find complaints about not being able to "find players" to be silly. People can find players for all editions and games of D&D and others so much more easily than they ever could before VTTs and the internet.Im sort of with this. I would say outlier instead of outcast. Normally, not a big deal you just grab a game and system that does suit your preferences. However, with D&D's oversized impact on the hobby in general, it makes having a committed concern to its direction, and thus disappointment when it moves away from you, a popular opinion. Nobody wants a tiny pool of players to choose from. So, that anger gets placed at the feet of WotC.
I think the above was much more drastic back in '08. Now with the rise of VTT, crowdsourced indie games, etc... It's becoming less of an issue with every new iteration of D&D. YMMV.
But I think what we're finding now is that because the total player pool is so much wider... players have begun condensing it themselves by getting more and more nitpicky about every single little game facet that they want. It's not enough to just say they want to find 5E players (which is quite easy in these days of VTTs)... but now they are saying they want 5E players that won't use Tasha's, will only play non-magical characters, no races other than these 5 specific ones the DM has chosen, and are okay with using the X, Y, and Z house rules the DM wants to incorporate into the game because they don't like how WotC's rules do them. And then when all these contingencies do not produce a viable player pool... then they complain that WotC's rules changes have made it harder to find players.
