Well, I am on a very very restrictive budget and have been since I became disabled.  As a result I mostly have to rely on freebie stuff now.  But when I do use a specific commercial package, I try my best to credit it.  Some of the commercial stuff is a bit pricey nowadays as well, which may be related to lack of credits.  Could you be a bit more specific as to which of your products are not being credited?

Quote - Well, it's been a while since my last product went to market.  I thought enough time had passed that I could search the galleries and marvel at all the renders made using my product.  

Searching came up empty, so I looked at every buyer's gallery to see if it went uncredited.

Lo and behold, nobody has rendered my product, credited or otherwise.  Now, mind you, it's a good product, I use it myself.  It renders quite nicely.  I'm trying to stay clear of self-promotion here, but you get the idea.  It's a fine product.

Some brow-raising discoveries have me wondering if you Vendors have had the same experience, and for the end-users, what gives?

The money comes in, and that's all well-and-good, but there is an additional satisfaction that comes from knowing the customer got good use of the item.

I guess this isn't much of a survey, but would love people to weigh-in on this topic.  

As for me, I'm sure I've bought some things I haven't gotten around to using.  I'm also pretty bad at giving credit, since I'm at about 20 gigs off stuff and half of it requires an endless search to figure out who made it.  I render from time to time, but not enough to use everything I've collected.  I DO have a gallery though, and it does expand, and some merchants can find their stuff in my end-results.
