I just can't think why you might have trouble convincing people to try it :p 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.

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).
