Telling people they are wrong, or idiots, or entitled, is probably the quickest way to alienate them and lose all support instead of gaining it.
Bottom line, just admit it, you hate anything that is not 100% open source, which is your opinion and right to do, but that doesn't make it the only option and if Nvidia provided a solution that allows you to work with their GPUs, it is you that is wrong here. They are the bigger fish, thus they get to eat you or at least push you around. Basic life lesson.
You would have been much better off writing an article simply asking for a few passionate Nvidia user that wish to take over Nvidia support if they would like to see it continue to work in Sway. Instead, you write an article that alienates the entire user base. That's a pretty shitty thing to do and a reason people seem so unwilling to work with a lot of FOSS maintainers, because the truth is, they act like the entitled ones, as your article clearly does about you.
