I 100% use LSPs and other modern tooling, but I find it weird as well too. Like, if I found out a favorite author of mine wrote everything on paper first I'd find that amusing and quirky.

Obviously a developer not using LSPs can be competitive against someone who doesn't (though that's not always the case).

Though if someone is truly bothered by others tool preferences, they should take comfort in the thought that if things really are as they believe, then these people should be driven out of a job for failing to keep up with the times. "Great," you should think, "one less person of competition on the market."
