So? Nobody is preventing those users doing what they want with their key bindings.  You're making a general purpose argument against having default key bindings at all. Why don't we just ship Emacs with an empty global keymap so we're not imposing on anyone?

Metrics with nontrivial opt-in suffer from selection bias. The sort of person who goes out of his way to enable telemetry is the sort of person who's going to do more customization than the average user.

So? How does providing default windmove bindings make your life worse?

They're not convenient for anyone if left unbound.
