Not saying this is wrong but I haven't encountered any ads when I use Ubuntu on WSL2 through a terminal. Does it happen only in the "proper" desktop version? What do the ads look like?
AFAIK it's just a blurb telling you that you can get Ubuntu Pro. Not exactly a real ad; it's just that some people don't like the fact that Ubuntu can advertise its services in its distro.
I just had to disable this on a machine earlier today. They list all the packages you have that could receive additional security patches through Ubuntu Pro. I'd much rather see 'All packages are up to date.'
