Both things can be true.

The knee-jerk hysterical reaction to any talk of hardware roots of trust on Hacker News is getting tiresome and I expect better given the reputation of the site. It actually reminds me of old slashdot.

The software running on such devices is usually proprietary and never installed by the user. That is user-hostile.

What software?

The firmware implementing TPM functionality, which definitely exists in at least some cases:

For ASIC-only devices, the keys are burned-in, which is user-hostile too.

I'm not seeking to criticise this product, I think this is a great development. But, for almost all people this is shifting from one kind of "trust me bro" to .. another. We're not going to be able to formally prove the chip conforms to some (verilog?) model, has no backdoors, side channels, you-name-it. We're in the same place we were, with the same questions. Why do we trust this and the downstream developments? Be…

Look up bunnie's talks about hardware security, its basically impossible, there are too many parts to the chain leading up to the end user holding hardware in their hands that are all attackable.

Another thing to look up here is the bootstrappable.org community. They started at the software layer, how to create binaries from scratch without using any existing binaries. They are also interested in the hardware layer too.

Is the firmware in my NIC user-hostile?

... and usually deployed in a user-hostile manner.

Any evidence of this? Computer security was a complete disaster before hardware roots of trust became standard.

It is still a complete disaster. Nobody needs the password to your bootloader when it can access all your data through your web browser.

That isn't possible.

The firmware in one of my NICs for sure is. The vendor says they're not bothering to fix it, and nobody else is able to.
