You can still get all of the same benefits from an essentially identical system where you DO know your master key that controls the security on your computer.You need to hide the master key when you want to be able to do something only on your machine. If you do know your master key, it means other people can know your master key and replicate it on other machines. This way they can steal things from your machine you want to have locked to your machine. An additional issue is that Trusted Computing defeats the GPL. Under Trusted Computing source code often becomes entirely useless. If you attempt to modify Trusted Computing GPL software then the Trust chip will detect this modification and the chip will forbid you to read any 'secured' files.They can forbid you running the modified code on the same machine but they can not forbid you adapting the code to run on machines not having a TPM chip. So yes they forbid you one of the reasons of the existence of the GPL e.g. to be able to bug fix code for the machine but they can not lock down the code. Staf.
