There is a fundamental flaw in the argument though. All the organisations mentioned (my employer's competitors) tend to advertise in the classified section of the magazines mentioned and of Flight International. These do not have written articles in the facing pages, and in fact are a stack of pages with only adverts. Check out the magazines.
The exception would be the newspaper-style "Flight Training News", which is the closest thing we have to a trade press so I think the editorial slant is acceptable and expected.
