It amazes me how many people think they know the Internet, service providers and how it all works when they don't. For example, the company I work for is also an independent ISP we promote ourselves as an independent ISP; however, in reality, we have bought a pipe through wholesale (BT Ultimately), and so while we get that statement: "You do our broadband........." we don't really. Apart from [some] cable companies, everything goes through BT house (British Telecom) in London in the UK.
The only way you can avoid BT is by living in Hull or using companies Like Virgin Media; however, even they piggyback off of BT in some areas, and that's before we even get to 'Cloud Services' where you find out that your hosting company is, in fact, keeping your data on an AWS etc.
