Here's hoping. Intel did a great job hiding the thing and making it all but impossible to remove (at present if you nuke the firmware, the CPU will totally fail to initialise. Thanks Intel!). That said, we're talking about an embedded device with very low-level code, and any 'disabling' code is probably going to be distributed in binary form. Stands to reason somewhere along the lines, someone is going to turn that around for their own benefit.
In tin-foil hats, we trust, more like!
