Don't be so generous in your assumptions. Meta simply stole the username because they could, and gave the old owner nothing in return. Or if they were lucky, maybe the band got a few Meta branded t-shirts, as was the case for one of the other victims from the article.
Seriously, look at that list of all the times Meta stole people's handles. Why would this time be any different?
