Earlier quoted context omitted.
The policy wasn't universally mocked. Maybe you're in some specific subcommunity, but browse around a little. The opinion I heard most was that the policy is understandable (there is such a thing as advertiser-unfriendly content) but people want more transparency from YouTube so they can work the system effectively.
That's true, but the point that many made (and is correct) is that many forms of content cannot be advertised upon under the new policy. In fact, depending upon how YouTube interprets the policy, they can probably block monetization on any video they want, and still claim to be merely enforcing the policy. Finally, it's quite unlikely that this policy will be implemented fairly. If you want evidence, merely know that…
Another thing you need to realize is that this is all automated, they don't come and manually remove monetization from your video. Yes, the algorithm could potentially be wonky, but again, it's in their best interest for it to be good.
Everything that has been spouted so far has been senseless propaganda and none of it is backed by any actual facts.
