Google is concerned with paid advertorials with do-follow links and has been penalizing paid advertorials with do-follow links for at least a year and a half.
Uh, no, google doesn't care about advertorials, they care about the links in them. I've never heard about Google commenting on advertorials without dofollow links. Google appears not to care if you buy advertorials without any links in them, i.e. just for brand hype, product launch or whatever.
As far as your ideas about combating paid links in advertorials - they have already been broadly applied on websites such as press release services. The reason google is telling the webmasters to nofollow themselves is because they have already done as much as possible on this and will either try to scare some webmasters via a few publicized manual penalties or try to tweak something in the algo to appear as if it's penalizing such links. FUD is the only tool they have in this case.
