This is plain false. While it's impossible to guarantee a 100% code reviews, the number of bugs and vulnerabilities found, reported upstream, and patched by distributions (especially Debian) shows that code is being reviewed.
In both points you conflated, again, disdain towards software and disdain towards users.
> I take it you've never been on the receiving end of the "Oh, you use _Windoze_" comments
Actually I did. Clearly those were not insults meant against me as a user.
Just like stating "beer is disgusting" or "I hate Samsung" is not insulting me for my drink or monitor brand choices.
> Free software activists and advocates are often accused of "user shaming".
What do you mean with "shaming"? I've been at many DebConfs and I have never heard any other DD calling people names just for using some closed source software.
That's a hard pass for me!
