But you yourself bought up convenience in your original comment. If your argument is a purely moral one then no need to specify how little fiddling is required to get LSP working. But I do think if your only argument is yelling at people about it being immoral to use VSCode you ain't going to get far. Why not talk about the cool things Emacs has while acknowledging the things it still has that could be improved?
VSCode is open source by the way, MIT not GPL but you can go compile it yourself (or use VSCodium).
