Whereas with wikipedia, unless a dedicated team of editors who are contracted or liable to vet _every_ change. Possibly only for the UK, who get a special 'only with vetted edits' version or some such, I don't think wikipedia would be interested in making such a thing.
Separate from that, wikipedia has various pages on (conditions related to) our sexual organs, as well as lots of articles about politically contentious things. I don't think they are particularly interested in filtering that either.
In contrast to news channels, most of which would have no particular complaints about a bunch of rules about content. As a rule your 9'o clock news isn't going to just casually show frontal nudity (except e.g. Germany because they're fine with it).
One obvious problem is all those words in single quotes: Who gets to decide? Evidently you aren't happy with whomever decided how far you can go with the content shown on the news, and I concur that it goes quite far. But the point isn't about the current standards being applied. The point is whether _any_ standard can be applied at all.
To news: Yes. To wikipedia: Not in a way wiki foundation would accept.
