I remember piping up about all those things. But the excuses were everywhere.
- Oh but you can turn it off so it's no issue (secure boot). Well yeah but more and more stuff just won't run then (eg iOS apps on Mac). It will become the norm to stay inside the fuzzy walled garden just like it already is on phones. And if you stray you will just be blocked from any app that does something useful.
- But companies need to be sure you are who you say you are (attestation). Yes but they will abuse that power if they can profit from it.
