it does restrict you.
In terms of the technical connection it is pure Openreach between you and the FTTC exchange. So in theory any FTTC supplier. In practice things are very different.
Basically there is no difference in ISPs' policies between FTTC and ADSLx. Sky and TalkTalk require you to have line rental from them if you want their FTTC. So do BT in all their advertising, though they do have a hidden Solus product line which does cater for your line not being with them, and I think includes FTTC.
Plusnet only do deals on bundled line and broadband, but would allow you to have FTTC on a Post Office line. At full price plus £3 I think, it used to be plus £2.50, and with a setup fee.
With smaller ISPs it depends which one and which FTTC product you choose from them.
