I don't see TFW promoting KOs, and usually only see news posts about KOs to alert people of new ones like we do in our KO section.
They do have lots of news posts of Unauthorised "3rd Party" items by non-license holders, but that's such a grey area, I don't want to start up debate of that again.
I personally don't like seeing it on their *Transformers* news page, which should be for news of legit or licensed Transformers items... but "3rd Party" are no more "Knock Off" than Hasbro producing a vehicle alt-mode that resembles a real-life vehicle without paying a license fee for it.
To their credit, Hasbro and TakaraTomy do license a lot of their real-life vehicles, which they easily have found ways around it to save money, but when they produce something we refer to as an "xxxxxx" alt-mode that isn't licensed, it is similar to referring to a 3rd party toy as a "not-xxxxxxx" toy. Everyone knows what it is meant to be, but the producer of the item didn't get licensing or permission first to profit from someone else's investment or design.
So for now, I'll follow Hasbro's lead. If they don't crack down on Unauthorised items, I don't see a reason to do it... but they won't dilute our "Transformers" News and discussion sections. If one of those items was eventually licensed or Authorised by Hasbro, then it can be included in the Transformers sections here.
