Trusted computing and TPMs aren't inherently bad. Like all issues of trust, it comes down to who the trusted parties are and what they're asking of you.

So for example, let's start with the idea of a work computer. Say you work for a bank and they issue you a laptop. In order to access all the sensitive data related to a bank, certain guarantees must be made about the environment. The hard drive must have full disk encryption (FDE) so that if it's ever lost or stolen, the information that may have been on it can't be compromised. This is not your laptop. This is not your environment. This is for the most part, totally fair.

Now let's consider Microsoft and your personal device. Microsoft is forcing you into their trusted environment by requiring online accounts and TPM/SecureBoot. And how do you benefit? FDE through BitLocker, sure. But you know there are other FDE solutions and BitLocker results in you losing control of your keys because they are automatically uploaded through your online account to Microsoft for "recovery" purposes. ~Source ~Related What Microsoft is really saying here is that they have a trusted environment, and if you are to be a trusted party in that environment with the "privilege" of accessing their software and services, you must submit your personal device to their rules. Are you starting to feel the icky vibes here?

This is made worse by TPM 2.0 supporting remote attestation.

This of course raises the question, verified to what degree and to whose standards? Are they simply trying to protect us from maliciously crafted software, or is it DRM to prevent running pirated content, Trusted Platform Module (TPM) 2.0 and Secure Boot for Call of Duty. Of course this is ostensibly for anti-cheat, but you see how quickly that moves adjacent to other purposes. How much are you willing to give up to maintain (a sense of) security?

EDIT: One final point. Trusted systems are the general security engineering concept of protecting systems through enforced policies to achieve certain levels of trust. Trusted Computing is a very specific set of technologies with a board of directors worth taking a quick look at ...
