I think they give away their real complaint when they mentioned "anything to the right of far left" as if reddit only allows far left views.

Not the moderation but the general sentiment.
You always see users going on and on about Linux for every slight mention of Microsoft or Windows.
Same for other stuff like news. Everything is about the US and rarely anything else.

Everything feels politicized. And if not it's an OS war.
And if not that it's "Why are you not using this piece of software" solely because it's (F)OSS.
But if you for example question why they are using Plex (which isnt foss) they deflect by saying Jellyfin is not secure enough.

As if they are targetted by state actors trying every zero day to gain acccess to their infrastructure.
