I think he knows that and has mentioned the results will be somewhat skewed (or maybe he mentioned that in an email to me). For arguments sake, 10% have said they have zero subs.
I think the point stands and the reality is somewhere in between the numbers discussed here. I find that people who like Sirius XM either like it a lot or are simply content. 4 people in my immediate family have subs and 3 of them have multiples.
Take it for what its worth but, I am sure we can all agree that some number of subscribers have multiple accounts and the way Sirius XM track subscription numbers is a little misleading.
The numbers are simply not as good as Sirius XM would like us to believe. I am not looking to speculate numbers or have an argument here, just speaking generalities... generally speaking the numbers aren't as good as what is reported.
