Presumably it wasn't a concern when they started and became one later; after all, they changed the license.
AGPL doesn't prevent others from reselling your software no? I thought it only mandated that they also release their own source modifications.
He seems to claim 3rd parties are offering bearblog commercially without modifications (or with useless modifications, like just a changed name).
