First off, the wording in the first post of this thread states, "...incorrectly having access to RSN channels". Which makes it sound more like some AT60(AT100) customers are/were getting RSN's without being a part of the proper package.
Secondly, the wording "Should those customers wish to continue receiving RSN's...", makes it clear that this is not a case of not being ineligible, but rather just the opposite, ...eligible(but not properly being billed for them).
I'd be surprised if this was anything more than some AT100 customers getting AT100+ RSN's, without having asked for or signed up for them.
