Then again, it's just an advert for selling beer - why would a company trying to sell a product run the unnecessary risk of running off too much market share by mentioning something like "the Creator"?
Sam Adams makes beer, it doesn't make government policy, so its use, quotation, paraphrasing, or whatever, of the Declaration of Independence is nothing more than the sort of puffery one finds in many other sorts of commercials.
It's a beer ad for crying out loud.
