Operating systems should avoid unnecessary politics

Yes. Exactly this.

I flatly refuse the request to avoid politics in my free software work. This is for a lot of reasons, but the most obvious is that politics is the main reason why I'm working on free software in the first place. The idea that there is some narrow set of (conveniently, often capitalist-libertarian and somewhat right-wing) set of politics that are "okay" for free software and all other politics have to be excluded is utter nonsense, and I will not be complying.

But I am still interested in finding ground on other principles that don't require that I adopt other people's political beliefs about such loaded issues as discrimination, such as a principle that authors of software should not use their power to act against the interests of the user. And I will advocate for that as a free software issue, because allowing people to be in control of their own computing is part of my politics. :)
