Fear the work of unpaid ad execs! They won't stop making adverts, it's what they live for, money or no money! The adverts will continue to be made, but now they will be made for love, and they will be extremely high quality! And if you think ordinary adverts are bad, wait until you see what adverts are like when they come from the heart!
I wonder if I should point out that your link says that it's when people stop being paid that quality declines. However, if "ads for ads' sake" became a thing, it would presumably look like propaganda, in support of whatever the advert-artist personally cares about.
