I agree with both.
In addition, Google is not concerned with paid advertorials, as such, but with paid links within articles. And they are concerned, because it's nearly impossible, when done right, for an algo to distinguish a paid link from free link.
The only way you can get "caught", however, is if a spam employee visits a website for whatever reason and sees a paid link and decides to manually penalize one or both sites. Again, assuming that it's done properly. If you have a link to a handbag site on an auto blog, that would be rather easy for the algo to identify as paid link.
