Google I can live with. I know they have all my data (and I've never been worried about them). I'd probably swap though, as Google cannot offer the service IDNet can (though could offer a subsidised price I guess).
I do though complain how BT and other companies treat their customers. So I'd feel let down if IDNet sold to BT. Then if I'm going to be stuck with having to have a large company managing my net, I would choose the cheapest.
While IDNet are separate, I know I'm getting a better service.
It's not that Notch sold, it's that everything he talked about before suggested he would not sell, and if it was about the money, we all expected him to make it himself too keep hold of the empire. I guess the stress really did get to him first. I just hope the stress of having the cash is less than the stress of having the business.
