Although I confess I do this occasionally, I do think it's bad practice to blindly copy and paste a dscription. However, I only recommend software I have actually used and if I haven't, I'll always mention this in my answer. The point is that pre-written descriptions are usually written to tell the (potentially new) user of the product much about the product's features with as little text as possible. I just see no reason why to reinvent the wheel and write yourself a similar description when you agree to what it says.

So no, I don't think this is a reason to downvote the answer. I think as more useful answers are submitted, those that aren't useful at all will submerge in upvoted answers thus solving the problem.

Of course, downvoting answers that only contain the ad quoted (statements without proper arguments like "It's the best, just because it is") would be proper. However if a quote contains proper arguments like "It's the best because independent consumer survey pointed out that 90% of the users are more than satisfied" I see no reason to downvote it.
