I would not discount government 'incentives' to BT. Hundreds of millions have come the public purse for contracts that were supposedly put up for public tender. BT got about 95% of them.

edit: there are other issues in the UK, like fibre tax, that makes the situation even more difficult for competition.

None of the other providers wanted to serve low value customers is the blunt reason.

I'm not sure that's the case, otherwise why would community driven projects like https://b4rn.org.uk/ exist if BT was serving low-value customers properly? In reality they're the company that doesn't see the value in investment there, completely counter to what the pubic purse was supposed to be supporting.
