I honestly would, and I've said it many times before, but GAF overall would suffer for it.
Being ad-supported means you get a wide variety of perspectives and expertise on here -- things that are really valuable like poors who have nothing better than to sit around all day waiting for iOS apps to drop .25 so they can post about it on GAF or people who spend days creating painfully comprehensive official threads (updated daily) for mediocre games.
No one who has any sort of a job or career would have time to even think about doing that, which is what makes the Freedom of GAF so valuable to everyone, even those of us who could "spare a dime" for it.
