Of course TPMs can be (ab)used for DRM, but the same property in general to many ideas in cryptography. We still don't say AES or RSA are tools designed to rest

Of course TPMs can be (ab)used for DRM, but the same property in general to many ideas in cryptography. We still don't say AES or RSA are tools designed to restrict your rights. AES and RSA are just algorithms, not implementations. I'd compare TPMs to HDCP, AACS, or CSS (the DVD one) instead.
