I don't know about intentionally designing that. It would violate contracts and have to be a hidden, but broadly conspiratorial activity. I have some professional experience in consumer electronics, and I remember when TPMs started becoming a required component for CE. It took several years to become commonplace; a slow transition from security by obscurity to sensible practices when devices started to be internet connected.

Nevertheless, from my experience, I'd say the TPMs aren't there for user security, they are there to keep Hollywood movies safe.
