Then google will use text to show ads.

Isn't Ubuntu doing that for at least 3 years or so in terminal during system update?

Text based ads would be less distracting.

Not if they're inline and you've read an ad before you realized it. Like a YouTube sponsor segment. lol

Fair. However, text based ads are also very easy to filter out using some sort of extension no?

Yeah, I actually use NordVPN (this comment’s sponsor) for this.

Remembering when Google only served text based ads.
