Vim does things at least as bad. Here’s something I wrote in 2020 that shows how the default Vim configuration can overwrite files created outside of Vim and cause autobuild systems to fail: https://lee-phillips.org/badvim/

And why my .vimrc starts with this:

    set nobackup
    set nowritebackup 
    set noundofile
    set noswapfile
