If only it were so. But no, there are plenty of sources out there that indicate there were other charges made too, such as on Steam.
And I wouldn't trust a thing Kunstler says on it either. It's her job to try and distort the truth about her client to put him in the best light possible. In an Al Jazeera America interview (where I was another participant having known Hammond 06-10 and targeted by him after an attack on the Political party I work for when it wouldn't become his anarchist haven) , she claimed he wasn't even part of the group until well after the credit card numbers had been stolen and used. The problem is, no good attorney EVER advises their client to plead guilty to something they didn't do, and by all accounts his legal team was top-notch. So either the FBI had plenty of proof, or were plea-bargaining for something bigger.
Problem is, taking credit card numbers and making charges on them is one of his 'things' (along with violence; either directly as with holocaust deniers and Daly Plaza, or indirectly via SWATing), it's what he was convicted of in 06 with Protest Warrior, except he was caught there before he could use it.
And even if they did just donate to charity, that's in some ways worse. fraudulent charges hurt charities, and cost them money. So he "stole" from them too.
