It is not central in security nor in reliability! It provides only a
certification mechanism, and has nothing to do with securing the system
from outside. And it has absolutely nothing with the reliability of the
system...
So the chip, for what I know, is totally unable to give anyone control
over the system. If there is the slightest chance of it, just advocate
very strongly for the TC chip to be removable and replaceable.

Which is a very strong flaw in it's design. It should be possible to
change it, I think.
And if you're not happy with it, maybe you could burn it.
