You're probably right or not.
First I just present a result of a test conducted by a credible magazine. The test parameter are well explained and well detailed. All seems credible .... but perhaps indeed biased.
I have honestly no idea of the quality of this tire (Cooper). In my case, I am very satisfied with my BFG MT (255/85R16), BFG AT (31/10.5R15), Toyo MT (265/75R16) and AT Yoko(31/10.5R15).
Finally, I took some time to check the last 3 Overland Jounarl issue.
''Gear'' issue 2014 : 1 ad for Falken tire.
Spring 2014 : 1 ad for Falken and 1 ad for General tire.
Summer 2014 issue : 1 ad for Falken and 1 ad for General tire.
... we'll see if there will be more Cooper tire ads in the future ...
