I'm afriad "the guy" is not absolutely right. He would have been had the article been written about a year ago. Virgin has been removing the slogans from its aircraft since about June-ish and the only ones that are still on are the "fly a younger fleet" ones that don't involve four engines. Do a simple search on A.net or Jetphotos and you can see for yourself. Basically this guy's article is completely pointless since he's complaining about something that no longer exists.
