Yes, ads would be unavoidable, but there would be the possibility of distributing the revenue more fairly. Otherwise, the only option would be to accept donations to accounts, but no one would likely use that. I’ll say it again: ads are not an option in the Fediverse, not even in a transparent way, and not even though ads not only finance the internet, but have also traditionally been a major source of funding for things like quality journalism (subscriptions have never been the main source of income here). Nevertheless, it remains a fact that good content costs time and skill, and therefore usually money. Without monetization methods, there will always be a shortage of content that is more than just reposts from elsewhere. So it seems to me to be an unsolvable problem. But of course, I also completely understand why the Fediverse fundamentally rejects monetization—at least in the form of ads.
