It's a good incentive, methinks. They/he seem intent on rebuilding the community's trust, whatever good that'll do them. ;-)
While I have something of a suspicion that the t-shirt issue will have little to do with whether or not they're successful in the long run (du-uh), I'd say it's a good first impression to make.
Now, a few more suggestions for the text:
"I'm not the new Amiga Inc. CEO - it just says so on my businesscard"
"This is what a $50 t-shirt looks like"
"Clothing, Apparel, Merchandise"
"2 years in the making"
"Putting a thousand monkeys on sewing machines may eventually produce a few t-shirts but it's not something you're going to want to wait around for, and you don't want to be responsible for cleaning up the mess in the meantime."
