I blame (in part) the linux popularization approach that turned to drama to create a more compelling narrative. The now defunked linux action show for example. Having an opinion is cheap. People who have never contributed a line of code or donated a cent to a project think that by being super opinionated about systemd vs upstart or Mir vs wayland, that they can virtue signal how "l33t" they are. Then they justify their strong opinions with arguments about "fracturing and redundancy" but never anything technical because they actually know nothing. Telling those people to GTFO is both cathartic and better for the FOSS community. Right on Mark!
