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.
Before I respond to your comment, allow me first to acknowledge the following injustices happening in the world:
* war in gaza
* war in ukraine
* civil war in sudan
* civil war in yemen
* civil war in myanmar
* ethnic violence in syria
* insurgent attacks in nigeria
* insurgent attacks in congo
* attacks on protesters in Iran
...
Wait, what's that? You don't want every comment to start with some sort of land acknowledgement-esque disclaimer of all injustices happening in the world? What are you, some sort of gaza war/ukraine war/sudanese civil war/ ... sympathizer? Tens, if not hundreds of millions have been affected by the event listed above, so at the very least you can spare a thought for them before discussing about some text editor getting compromised? You might argue acknowledging the war in gaza is beating a dead horse, but do you think the median HN reader has thought about the civil war in myanmar in the past month?
