Corporations cannot be trusted. Proprietary software is bad enough but proprietary drivers is on a whole new level. You really have no idea what those things are doing unless you reverse engineer them.
Here are example of corporations essentially pwning your computer with their "justified and trustworthy" software:

Shipped a browser stealer to users and exfiltrated on an unencrypted channel the usernames and passwords of users they deemed to be "pirates".

Screenshots your computer screen and exfiltrates the picture to their servers.

The driver literally provided privilege escalation as a service for any user space executable.
As far as I'm concerned anyone who trusts these corporations with kernel level access to their computers is out of their minds. I don't trust firmware but at least it's contained in some isolated device.
