For example, "And music streaming services offered by Google, Deezer and Spotify have said they would remove music that incites violence, hatred or racism."
Now these services have put it out there as policy someone has to define what's violent, hateful or racist in music. Racism? Ok nobody's really going to bat an eye at that disappearing.
Violence and hatred though? As an off again on again heavy metal listener.. almost literally every track could be described as violent or hateful. That's the genre. The same could be said for other genres and their sub-genres. Rap comes to mind. Is Eminem next on the chopping board?
Music was the easy example, there's other examples available for the other services (registrar, DNS, hosting, CDN) as to why making this policy is a bad idea. Now anyone needs to do is convince someone at the corresponding target that a site is similar enough that it should be taken down.
South Park had a two-parter that addressed this exact problem [1][2]
