If you’re not trying to change other people’s behavior, what are you doing?
Finding sources you can trust is helpful. For example, I trust the ArchWiki and POSIX.1-2017, and I follow instructions I find there, which helps me accomplish things without having to spend time thinking about the rationale of those instructions (since the instructions have probably been independently reviewed many times, and if there was something wrong with them I’d probably have heard about that). It would probably also be helpful to be able to trust instructions at https://libretube.dev/ for similar reasons.
I don’t think keeping my thoughts to myself is a good idea, since I don’t want other people to disrupt my life (unintentionally or intentionally), and giving notice about how I want to spend my life is helpful.
I do think my comments are helpful (and that helpfulness is relevant). If I didn’t think that I wouldn’t be commenting.
