My understanding is that you could draw a legal distinction under current law with those words, but only if this part falls under the word moderation not the word editorializing:

> that editorializing something such as [...] removing content or context

I suppose it would be permissible to draw a line where you could delete all or none of a users content, but not some, since that does sound content neutral. I don't believe anyone has drawn such a line though in law (and it would be quite the strange line to draw).
