My opinion is that open source documentation is like polite dinner conversation: It’s not the proper place to discuss politics.
If an author wishes to use their open source project as a platform to discuss politics, that’s the author’s prerogative. But then, as perhaps in this instance, it could be to the detriment of the project itself.
I'm going to place the blame on the party committing the crimes, not the person exercising free expression.
See something in the release notes of an app you don’t like? Go use a different app, give your money to a different entity. Don’t spend your time and resources messing with the producer or user of the thing you don’t like.
This of course runs the risk of maximal polarization once everyone has filtered themselves into their neat and tidy little bubbles. What happens then, everybody leaves each other alone? Or do the echo chambers slide into further radicalized detachment from each other?
To get back on topic though, I think conflating using Y app with holding X position on a topic like politics is a dangerous road. Which is where I think having a dedicated space for those politics makes more sense. Whether that's a blog, twitter, etc. It allows those most dedicated to you to know you better without making the product or program a political stance. But the developer is ultimately free to do what they want. So it's not like anyone here can tell the developer to change in any way.
