Legal Advice
I am surprised that nobody has mentioned the fact that BT has a huge number of lawyers on the payroll working (?) on wayleaves, conveyancing, contracts (for both customers and suppliers), disputes with staff (unfair dismissal, discrimination etc), compliance with statutory regulation (Elf & Safety and OFCOM jokes for example) as well as security and spying (sorry, tracking users' surfing habits to offer them a better experience). I would be surprised if they felt that they needed to seek opinion on the Phorm trials outside the company. The answer they were given by their own lawyers might reflect the desire to please rather than a considered opinion on what was, probably, something a bit outside their normal remit. They, BT, might be now regretting that fact,
