Did anybody seriously think SSN was going to last on freeview?! It's Sky!
Yes, for the same reason that cdvillafan mentioned above.
Personally, I refuse point blank to pay for subscription TV - especially to Sky. In the same way that I no longer use Gillette or Sure products because of their sponsorship of Sky Sports programmes.
That said, I suppose it could be argued that the TV licence effectively makes BBC a subscription service.
