He's created an incredible piece of software, and that's entirely within his prerogative to do this, especially because him being able to work on it full time leads to more work going into the system. He's made the world a better place so I'm not trying to criticize too harshly. But it's also super unfortunate right, because now if I run into an issue with Talon I am unlikely to find a search result of someone else who has solved it, but rather I have to interact with the creator of the software in a silo'd manner that will not be useful to anyone else other than me.
Tthreatening to remove x11 support entirely (as the article alleges) is also unhinged, yes. We're in a situation in which the best accessibility software is being threatened to be removed from a working platform because the author is (justifiably) frustrated with support requests that he cannot fix because of the transition to Wayland.
I expect that sooner or later we're going to get a better solution to accessibility than Talon, I'm not sure exactly how but probably using local LLM's in a heavy way.
