Doesn't every TPM use a unique key to prevent this exact thing happening? If you do rip the key off of it and publish it, they'd just blacklist that particular key as "compromised".

Rip the key off the cheapest android phone you can buy, or an old one after you've upgraded. Don't publish it - pass it to your rooted phone which can now use an emulated TPM.
