I expect this will end with a web API for remote attestation. Several standards for remote attestation are in the works[1].

Servers will be able to check that you are running a popular walled-garden operating system that does not allow sideloading before delivering content to you. That way they can know that you are not running an ad blocker, you aren't able store the video stream, etc. Something similar already exists with Widevine certification levels[2].

It won't matter that you have open source hardware and OS that can run any code, you won't be able to access most mainstream content with it. Devices allowing general computation will be useless to most people and thus be relegated to a small enthusiast niche.

I am disappointed by how little skepticism there is on this and how all tech media I've seen simply regurgitate the "TPM == 60% less malware, nothing nefarious going on here" claim.
