Nothing whatsoever to do with BSkyB, don't be silly. What that says is that the commercially-led, sponsored content of BBC.com is not content which they wish to (or would be allowed to) display on bbc.co.uk. "BBC Future" in particular exists because it is ripe for sponsorship by companies that want to be associated with blue-sky thinking and "building the future of tomorrow" - Honda, Huawei, etc. The BBC go to the extra step of blocking bbc.com in the UK purely because they realise that most people would not appreciate the difference between the two sites and just increasingly associate the BBC name with commercially-led content, which is deleterious to the non-commercial image that makes UK residents feel better about paying the licence fee.
