However, I'd be interested to hear more about why you think those unpopular opinions constitute "mistreatment." Am I guilty of something more than articulating my preferences and explaining our rationale for the decisions that we've made with our project?
Looking at the LibreSignal thread, you appear to be replying with the sort of snippy tone that I tend to end up using when I'm explaining the same damn thing for the Nth time to an audience that probably isn't going to listen. The only thing I've found that works for me to avoid ending up doing that is to summarise the explanation into (for IRC channels specifically) a factoid entry in an infobot or (for longer things and other distribution means) a blog post.
Or, alternatively, (1) people are being entitled as fuck because, well, people are people, (2) you might wish to consider writing up a blog post explaining the reasons for all of said opinions and then just post a link to it, since this will probably achieve just as much as trying to argue and will be far less bloody annoying for you, (3) IMO you're not guilty of anything and "carry on doing exactly how you're already doing" is not a choice I personally can see any good reason to fault you for.
(random free opinions of this HN commenter worth exactly what you paid, of course ;)
In general I'd prefer to see security relate libraries LGPL licensed to encourage their widespread adoption.
