You might as well block all the FOSS bros. Just stop using FOSS.
(FYI Lemmy is FOSS. The fact that people trying to get away from corporate greed also want to get away from other corporate greed seems like the expectation, not the exception.)
You can hate one FOSS implementation without hating the concept.
Honestly, the worst thing about Linux is the community of entitled elitists snobs that whine about anything that isn't Linux.
At one point I was tempted to install a distro on my home machine to expand my technological knowledge. But if it turns me into one of those fuckers, then I rather keep my social life. Doesn't matter if Linux is a divinely perfect OS or not.
