Privacy Concern -- and Faraday Pouch/Cage
So this firmware is embedded in EVERY one of certain model laptops?
Is each computer clearly labeled so the customer can decide to NOT purchase one of these computers?
Can the customer ask to have the firmware permanently disabled (e.g. a programmable fusible link) so that NO ONE can enable it from a remote location at some time in the future? What if the computer is sold to someone else...can that second purchaser have the embedded technology permanently disabled on demand?
ONE scenario I can imagine is the Computrace technology being abused by hackers or terrorists that gain access to Computrace data (by whatever means**) and then maliciously remotely delete data from hundreds of thousands, perhaps millions, of users laptops.
As far as I'm concerned, from a privacy standpoint this is also as bad as or possibly worse than having GPS tracking in your phone or RFID modules in your clothing, license plates, or other products. (search on "RFID" and "Katherine Albrecht" for related privacy info). The potential for corporate or governmental abuse is high.
**Including a lost or stolen laptop with customer data...read the recent "TheRegister" article on this re: TSA's "Clear" program laptop "disappearance", or how hackers recently infiltrated the TDameritrade client database.

As for defeating the technology on a temporary basis, a simple Faraday construct (pouch, netting, cage, etc) is all that would be required to prevent GPS from working. Some buildings are also constructed to prevent RF from entering/exiting thru walls, ceilings, and even windows. It would be a trivial and cheap exercise for "thieves" to setup a secure room in which GPS would not work.
