Let's discuss the parts you left out in your carefully constructed attempts at character assassination.
1) kitty has a template for issue reporting that the person that reported that issue didn't use, which means it isn't a carefully constructed report.
2) The issue is probably with kkp.el. I don't know about you, but I don't expect maintainers of open source projects to debug all issues in their own projects let alone unrelated ones. Kovid went out of his way to tell the OP exactly how to provide useful debug information. And he did so within a few minutes of the issue being opened.
3) The part you complain about is him saying he has zero interest in debugging kkp.el and emacs. Which is perfectly reasonable, again, why should he have an interest in it. He provided the OP with the means to give him information that he would be interested in debugging instead.
4) He then gets told that the OP would rather use some other terminal rather than provide the debug information he was asked for. Do you have any conception of how rude it is to go to some projects issue tracker and then state you are going to use a competitors product.
5) You tried again to insert an unjustified swipe at Kovid, with "the keyboard protocol he insists everyone get on board with". In reality that keyboard protocol is completely optional, an no one has to use it. The fact that everyone does actually use it, is testament to its being light years ahead of any of the alternatives and represents weeks of hard work on the part of Kovid to finally bring sanity to this corner of the terminal ecosystem. An effort he made for the good of the community. And an effort that has succeeded, since pretty much all modern/maintained terminal software support the protocol as it is clearly superior to the alternatives.
6) You were at best mistaken in making your claim that he doesnt like settings, but given you clearly have an agenda against someone who has done nothing to you other than provide the world free software, I think the default assumption is malice not incompetence on your part.
And yes by all means dont use kitty, I have a strong feeling that Kovid, who has been providing software used by millions of people for decades has reached a point in his life where he recognizes that some users cost way more than others. He is likely very happy that you and people like you give his work a miss.
A position I greatly sympathise with. People that report issues to open source projects need to remember they are asking for help, it behoves them to put in the maximum effort they can to reduce the burden of the free help they are NOT entitled too.
