How expensive would it be to rip the signing keys off the TPM? People used to do it to get free satellite TV but I imagine it's way more expensive now with the smaller transistor sizes

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".

I guess. But if the key stays private it could power a scraper or a proxy.

Just wondering just how expensive it really is to rip the key out (or to have access to the tools to do it)

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.
