My point is that YouTube does not employ creators, they offer a free service to creators without any guarantees. I'm also pointing out that YouTube does not want to demonetize videos because demonetizing a video costs YouTube money (they host and stream the video for free, but get no revenue in return) and any changes to YouTube's business operations that would reduce the amount of videos that get demonetized would very obviously benefit YouTube.

YouTube is not contracting creators to do a job, creators are uploading their content to YouTube at no cost to them, and in exchange, YouTube offers a cut of the ad revenue to the creators if YouTube can successfully monetize the video. Whenever a video is demonetized YouTube loses.
