Oh! Cool. I didn't even think of the fact it might be a Cable only restriction. Thanks for pointing that out.<br>
<br>
I wasn't being critical of that policy. T'was just FYI.<br>

Frankly, I think it generally has more benefit than harm for the bulk of users on cable. But you can make arguments in many dimensions about it.<br>
