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.
There is such a thing as being able to act and think in ways that aren't political in nature. Maybe not for you, but it absolutely is possible.
Politics are quite literally life-or-death for many people. War is politics. Access to healthcare is politics. Economic policy that determines whether businesses and careers succeed or fail is politics. Freedom to say what you want, believe or not believe in whatever religion you want, and be who you are without being imprisoned is politics. The people who make the most noise about politics are the people who are literally dying for as long as the rest of society ignores their plight.
If this isn't the case for you, it's because you benefit from the status quo. It is the definition of privilege to be able to "ignore politics". That means you are currently benefitting from politics. Of course you don't want to hear about politics, politics are doing just fine for you. And the comment you were asking to was asking you to reflect on that: if the biggest problem gracing you is hearing other people make noise about circumstances, the least you could do is deal with it. Your problems are trivial if that is what gets you upset. Other people are complaining about things that affect the outcome of their lives and you're complaining about... having to hear it.
