But how does any ISP then offer truly unlimited 330 Mbps on FTTP for £75 etc.?
Are you saying every ISP throttles their customers if they are not charging £300 a month for 330 Mbps?
BT Consumer are the only ISP to offer native FTTP 330/30 for less than £100 pm with truly unlimited usage. Due to their huge customer base, their light users will be subsidizing heavy users (whether its on FTTC or FTTP) and overall, BT will find their broadband revenue will cover their bandwidth costs.
However with smaller ISPs with a much smaller no of customers, even a handful of heavy users cannot be compensated for by their light users, hence why they either have data caps in place (eg AAISP, IDnet, Cereberus) or charge higher prices in £100's per month for a truly unlimited service (Fluidone). I remember IDNet a few years ago introducing a truly unlimited ADSL2+ service and nearly every freeloader joined them. Their network became crippled overnight and were forced to re-introduce capped packages. Some small ISPs have even gone bust by taking on too many customers on a cheap as chips service, eg E7even (pay £120 in advance and then not pay anything for 12 months LOL)
