Plus reduced support duration to increase adoption of Ubuntu Pro. Changing some packages ever slightly so they behave a little differently.

Switch to sudo-rs, uu-coreutils (rust based stuff), etc., etc.

It's not a Debian derivative anymore. It's something else.

Was not my cup of tea before, it's even more not my cup of tea now.

Switching to rust-based system software is very different from the clearly profit seeking (or control seeking which is just long term profit seeking) changes like ads and snap (with massive friction to not using snap).

Yes, but I prefer glibc + GNU Coreutils based systems in my installations. They're additional nails on top of the (fatal) ones like snap, Ubuntu Pro and MOTD ads.
