Pluton seems like the next evolution of the TPM which has been around for many years. Many (most?) modern CPUs have a TPM built into the CPU already (Intel PTT and AMD fTPM) so it's not a huge change from the status quo as far as I can tell.
pro-privacy people always seem to lack a lot of understanding around modern security landscapes and make a lot of assumptions that aren't true anymore (if they ever were).
I mean no offense, by the way, it makes me want to conceive a modern security primer for privacy advocates, because the community appears to have fallen behind a bit. like any community that focuses on one thing, that focus is often at the expense of other things.
