>windows TPM aren’t snitching on you?
The TPM FUD has really gone out of hand.
1. there's no such thing as "windows TPMs", whatever that means.
2. TPMs basically has zero access to the rest of the system. It's connected via a LPC bus, so there's no fancy DMA attacks to pull off. Over that bus the system firmware sends various hashes of the system state (eg. hash of your bootloader), but that's about it.

That's the specification. Have you actually monitored the bus using probes? Did you check that the TPM is only connected to LPC?
>Have you actually monitored the bus using probes
Isn't this the definition of FUD?

Dunno, you tell me. https://en.wikipedia.org/wiki/File:TPM_Asus.jpg
