Youtube has employed a pretty simple business model:

1. Reinvest all profits into company to promote growth.
2. When you start to reach the limits of growth, shift focus towards profitability
3. Everyone gets a yacht.

Before the 'Adpocalypse', Youtube treated it's fringe creators well enough that a lot of them were able to start creating full time, but the company wasn't profitable. To become profitable, they had to cut out the fringe creators that advertisers didn't like and lean on the sort of left-leaning, easy to digest drivel that advertisers were more comfortable with (ie - Jimmy Kimmel, Buzzfeed, Viners, etc.).

From a business perspective, I can't argue with it much, other than that they may eventually become so restrictive they squeeze out too much of their audience and end up creating their own competition. But as someone who loves creativity and the exploration of unconventional ideas, I think this shift has been a tragedy, as the environment that was a hotbed of developing fringe talent is quickly going cold, and while the ones that built a strong audience were able to survive through diversifying (merchandise, patreon, etc.), the opportunity for people to follow in their footsteps is fading away.
