When I see politics in software updates or documentation, nothing happens because I'm not looking to use the software for political activism. Maybe I tell my adblocker to remove the messaging, and carry on with my task.
I can engage with politics in a social context, when political messaging isn't interrupting something else I'm doing; that's a better place for activism, IMHO.
I almost always see activists using the argument that if I don't like the messaging then I'm part of the problem. Somehow I doubt that, given I don't mind messaging at all, where it's appropriate.
Political opinions about how things should be don't automatically dictate the actions that should be taken in support of those opinions. I can be mad about a law or a court decision and still have the good sense to, for example, not throw red paint on a lawmaker or judge.
Some behaviors just aren't helpful, and neither being right nor being upset changes that.
The good sense is your judgement. At some point a real, direct, disruptive protest is going to be the right solution for a big enough group of people. Peaceful protests are just a "we're starting to get there" signal. It's not like politicians normally say "gee, lots of people don't like how I abuse power, I guess I'll stop now". It's all about being collectively upset enough about status quo.
