Yeah I think a lot of us are conscious of the problem but you're right, the scale/critical mass isn't quite there yet hmm.
BTW I think one of the roots of our problem is that we seem to end up in these really weird "winner take all" distributions with only 2-3 main winners and rarely any serious alternatives. It happens with operating systems, browsers, it also happens within programming language communities, like Javascript, etc. Everybody piles up into one of the 2-3 most popular framework options (React, etc). Same thing for Linux distributions. etc.
It would be nice if we could figure out some sort of nudge or hack that would reduce this tendency and encourage more distribution of mass.
