Why phorm can fly with ofcom (satirical post, maybe?)
There's very high chances that some people who work within Ofcom have worked in other parts telecommunications industry.
In turn there are chances that there are people pretty high up in Ofcom that have worked at BT, or its previous incarnations, right back to the GPO.
It is possible that some of those people have a vested interest in BT's business success, as they may have recieved share options when at BT, or have just purchased them anyway.
BT is also a huge organisation that many other telecoms companies rely on, contractors and the like. Former employees of these companies may end up at Ofcom too, still with an interest in how BT does.
Then of course there's the fact that people that have worked in one industry for a long time will have friends who have also worked in the same industry for a long time. Sometimes these friends end up at the top of major players in an industry.... or worse, at an industry major player and the industry regulator.
Spookcall were new into the industry. Even if the old-guard did like the idea of selling forged-CLID to people (which their bean-counters would - it "monetizes" something else the telecoms networks can do), they are not going to let a new whipper-snapper into their industry.
