I think it is quite gentlemanly of craigsub to inform the speaker company of his intent to compare the speakers and publicly report the findings/results. It isn't an ethical necessity, IMO, but I do think it's a nice thing to do.
I also understand a company's reluctance to be included, even if they have carefully compared their speakers to the competition and think their offering is superior or at least competitive. In other words, I DON'T think that declining to be included in a comparison is necessarily indicative of a lack of confidence in their product. Everyone hears differently, performance of one speaker versus another can depend heavily on the material used for comparison, it's VERY hard to setup a fair test (though craigsub has done a very nice job in his comparisons), and I think as readers of these kinds of comparisons, it's all too easy for us to "overreact" to what we read. A company may wish to avoid the drama of such comparisons and just keep selling speakers at the rate they are used to.
I'll second the suggestion to try some Kef iQ3s. They can be purchased online for about $320 and I thought they sounded pretty good when I heard them.
