Texas Instruments comes on along with chief legal counsel for American Express, Visa, Discover, and everybody else... They were way, way outgunned and they absolutely made it really clear to Discovery that they were not going to air this episode talking about how hackable this stuff was, and Discovery backed way down being a large corporation that depends upon the revenue of the advertisers. Now it's on Discovery's radar and they won't let us go near it.
A great quote from the video:

The point is that keeping the information 'secret' does not stop the bad guys getting it - it stops the rest of us knowing that our information is insecure. If you're reliant on security by obscurity you have no security at all.

They can't withstand that scrutiny, as evidenced by the reaction of the lawyers, and by this video.
With a bigger antenna on this I can go into Starbucks and get the [details] of everyone there.
It's a shame discovery didn't feel able to nod at the lawyers, and then make the programme anyway - including the conversation with the legal people. Still, when you're depending upon ad revenues, it's not as easy as all that - at least in the short term. A good argument for the BBC TV Licence!
