Personally I would much prefer that developers lock poweruser features behind a paywall rather than plaster ugly ads all over the place. Making it a paid app works too, but likely 95% of the potential userbase would not try the app if they had to reach for their wallets first.
(I would leave the comment at that, but it would probably come across as a bit facetious and would fail any 'low-effort' test. But I genuinely mean it: remove the necessity to obtain a certain amount of money every month, and all of a sudden, people would be able to create, share, and enjoy for free.
As a developer, I feel more than sufficiently compensated by seeing people use and enjoy my work and thanking me. Getting featured on Hacker News would make my day; nay, year.
I just need to be able to eat and use a computer. I shouldn't have to prove myself valuable just to be allowed to live. I think everybody, regardless of what they do, deserve a livable basic income.
