Are BT competent?

Reports broke yesterday on fora (such as nodpi) and The Register that a PlusNet customer had received an invitation to join BT Webwise.  Plusnet is an ISP acquired by BT in 2006, but run as a separate business.  The current trials of the vile Phorm system of data snooping began on BT customers 30th September and were supposed to last for 30 days.  There had been much speculation that these trials either had not started, that they were late starting, and that BT were having trouble finding the desired naive users to sign up.

So, what's a PlusNet customer doing receiving an invitation to BT Webwise?  What kind of botched system is in place here, and can we actually trust BT to manage the hardware and software that Phorm have placed in their system?

In the meantime, the precipitous decline in Phorm shares appears to have paused, with the value levelling at about 180p - drastically lower than  the high point of over 3000p earlier this year.
