We are here to entertain! I accept that you don't like the brackets, but Axiom puts all its money into sound. The T bracked with a few screws is enough. As someone who has done marketing, you can appreciate that the extra screw holes are probably a liability limiter aimed at those who do not like to follow instructions.
As for the free swag, after 15 years as a marketing/trade show whore, I have gotten more than enough t-shirts, mugs, key chains, mouse pads, pins, posters... to last several lifetimes.
