I could not have said it better. I think it is great that the vendors seek out the forums' opinions, but it should be done up front and out in the open. I get highly suspicious when it is posted in a veiled manner, making you wonder if the poster is getting payed or in some form compensated to bring it to the forefront.
Perhaps, if the questions/solicitations were posted by the Administration rather than a individual member it would have more credibility to the forum members. This would ensure, that: the leadership is on-board with the information request, that there is no personal involvement or gain involved, and that the information was complete when presented and unbiased.
If vendors want unbiased evaluations then the Administration should be the one to provide a forum member willing to evaluate the product; performing the evaluation and report back with their complete, logical, and comprehensive review of the product.This would remove all doubt, that, the reviewing member or the member soliciting the opinions is doing so with the full permission of the Administration. In addition, it would guarantee that the activity is not in violation of any forum rules.
