Why are you trusting anything?
That's what TPM is fundamentally about. You talked in another post about it being for separation, that's a trust function, so clearly you know it's about trust. That shows that this comment begins disingenuously.
Open Source TPM software and hardware exist, and are under the user's control in a way that any other TPM is not. Not every motherboard has a TPM slot, but boards with them are not hard to come by, so it is feasible for users to have a TPM that they actually do control. Neither the TPM in your CPU nor the average add-in TPM is actually that. Being able to remove things from it is not the same thing as being in control of it, although it's a part of being in control.
