My experience is almost the same, though Axiom contacted
me after the 30-day trial period and I still haven't used my credit!
I don't think Axiom really advertises this, as they don't want potential Axiom purchasers to feel like they can't trust their host at a demo.
I feel confident in saying that the very large majority of us would give a demo just because we believe in the product and it's a nice way to spend an hour.
Any credits that Axiom passes along are really just "icing" and an after-the-fact "Thank You", not some hard form of commission.
