Certain magazines (Time, Newsweek, The Atlantic, ...) have journalistic responsibilities. Web sites like troyhunt.com do not. This is the crucial difference.

I don't care that a commercial site is trying to sell me stuff. I do care that journalists -- who serve a crucial political and social function -- are actually peddling widgets for the ACME corporation instead of acting in the public interest.

As such, advertorials are a problem in journalism, but not in commerce (provided they are well-labeled, etc).
