I'm worried that while this sounds plausible at first it also seems to run directly counter to how many of the most popular channels on YouTube got their start. Most times when I've been a subscriber to a channel before it took off, the channel always begins with a small, tight knit group of fans that appreciate the content being created. The channel owner may not even run ads and sometimes doesn't have the sense or skill to edit their videos down. The channel will exist in this state for quite some time before it begins to attract more attention. How many promising channels are going to be strangled in the cradle by a poorly calibrated algorithm that thinks they aren't commercially viable?

I'm afraid that if a policy to terminate channels early and often is pursued then we will end up with a YouTube entirely populated by channels that just seek to maximize engagement at the expense of quality. This is sad but YouTube has been on the decline for some time, there is still a lot good about it but they seem to be intent on transforming it into the antithesis of what made it successful in the first place. Same old story.
