Maybe, but some of my favourite channels do YouTube as a full-time job. Maybe they would still post part-time if they couldn't profit off of but the videos would almost certainly be less-frequent and be made with tighter budgets.

But even then I find it hard to believe. I subscribe to a bunch of seemingly for-fun channels but most of my favourites have by this point become full-time video creators. GCP Grey, Captain Disillusion, Technology Connections, Tom Scott, Veritasium...

It is true that money can corrupt, but in this world you also need an income, and if you need to devote a lot of time to get income from a different source then that only distracts from the time and energy that you can put towards making videos.
