I had just switched to this one when I discovered the problem, so was under contract for the next couple of years, and it's not like they advertise this as a feature where you'd have made that choice beforehand. Also, I didn't just need "an ISP" I needed a high speed connection and at the time my previous provider said they didn't offer that to existing customers, while the handful of others appeared to only offer 1/10 of the speed I wanted or only offered it bundled with tv/sport packages (I don't watch tv)

Since then City Fibre completed their rollout and I'm no longer an existing customer with BT so now I _do_ have a choice.

But bigger picture here: I mentioned my setup on a thread where a country is mandating all of their ISPs do this. Sometimes you don't have a choice.
