No it is not, but I am fairly sure that is one of the main use cases. And you have a uniquely identifiable machine which creates new security problems.
We also know from smartphones that manufacturers can indeed be motivated to lock bootloaders. I think the main reason we don't have that on PC is that there are still multiple manufacturers and legacy considerations.
I cannot read the minds of Microsoft, but I have my assumptions that I believe are quite safe.
https://trustedcomputinggroup.org/ has rebranded themselves because they got a bad name. Justified in my opinion. People have identified the motivation on day one.
But again, yes, it can have some security advantages against the numerous disadvantages. I think it is bad for open computing overall. There are certainly mechanisms to secure your OS that don't rely on TPM. It may benefit you, but I would actually like to see it removed from my machine with all the consequences (which would be not being able to play DRM protected media).

Aside from that it remains true:
