I must say I do not understand the whole "you have no imagination" critic. First, some people do not have a great imagination. Not their fault and they shouldn't be punished for that. Secondly, time is a finite resource. Thirdly, I find a lot of printed material to fire up my imagination. In the ecology of monsters I often found seeds of adventures or encounters, like I have by reading novels, watching films or playing other games.
The whole argument just sound arrogant. And I should know, I'm an arrogant bastard.
I agree, that's a lame argument. I think of myself as someone with a pretty good imagination and I still would be interested in professional resources - one, because these people do this for a living and are likely more imaginative than I, and two because it would save me plenty of work even if I'm just pulling out encounters or inspiration for my own purposes. No one becomes a great storyteller in a vacuum and as a DM I like seeing what others are doing with the game, even if it only reinforces that I want to do something differently.
Ultimately though I just think it comes down to a business decision re: where to best channel the talent's imagination - is it better for them to focus on tabletop rules supplements, campaign settings and adventures, or video games? I can't really fault them for deciding to invest cash that could otherwise provide plenty of resources for the tabletop game elsewhere if that "elsewhere" is the $93 billion dollar video game industry (compared to pen and paper RPGs' $15 million size last year).
