I suspect that the Sky satellites can only transmit data to the consumer, not receive it.
Satellite BB is poor choice. It rarely supports uploading direct to the satellite so the consumer is still reliant on whatever ground-based BB they have for uploading. This can often cause bottlenecks downstream due to congestion in sending ACKs.
In addition there is lag. Geosync satellites orbit around 36,000km above us. The laws of physics mean that 240ms gets added to your pings (120ms from ground station to sat, then back again).
You are also in effect sharing your downstream connection with everyone else within the satellite footprint. Satellite broadcasting can offer a lot of bandwidth but it isn't unlimited. Sharing it with an entire country-or in the case of Eurobird the entire continent-is not sustainable. A couple of gigabits bandwidth sounds good but when you're sharing it with a couple of million other people it's not so hot.
But the real reason is likely cost. Sky don't own any satellites. They rent space off satellite providers. I doubt that the economics would make sense. In fact a lot of people don't realise that most of what they watch through Sky is not even broadcast by Sky
Personally I detest the idea of satellite BB as a general solution. I accept that it's good if you're stuck in the middle of a desert or a jungle but not for the UK. It's horribly innefficient to send a data stream to 30million homes and businesses when only one of them is actually going to be using it.
