Yeah it is crazy when I noticed Ubuntu created a ~/snap folder that is required when anything is installed via snap. People defend placing application data/config folders in ~/ because they're old and it's always been like that, but Snap is brand new and they still neglected to follow the modern standard.

Other "new" softwares that fail to follow best-practices by putting top level files into ~/ just on my laptop are: npm, Ansible, pylint, docker, steam, rustup+cargo, vscode, IDEA IDE, Zoom, AWS CLI. These applications have no excuse.

Also I agree on the Documents, Music, Video, etc. I hate upper case letters in my folders, so when I do a reinstall I delete those and restore my backups from the lower-case versions.
