I used to think Purism was a sham, but now that the ME can be neutered I find it an acceptable compromise.
Also, this is a laptop, so a diff class than server/desktop models - so may not be fair to even compare them ?
This is unique. Of course, it's a machine targeted by Libreboot:
https://libreboot.org/docs/hardware/c201.html
I guess that if you install GuixSD, given all binary packages can be verified against the source, and there are some decent sandboxing facilities you can get pretty great security.
If you wear a tinfoil hat then you're going to be better off with a libreboot laptop, but you have to accept that you will never use a computer made after 2008.
I think that the niche that a Purism laptop fills isn't worth the price premium. A laptop from a main vendor plus a security conscious OS install (full disk encryption, two factor authentication) is fine for me.
It is literally safe to assume that every single device is 100% compromised and the 5eyes, can if they wish, monitor every single thing you do, based on these issues, correct?
But then, you also have to think that every service that you use, outside of your own 100% controlled purview (I.e. Literally any cloud service) is also summarily compromised to the point that you cannot say that one is completely secure...
Would this be safe to say?
I'm personally not worried about the 5eyes (but anti-gov activists should be). I'm worried about the smart kid who can use metasploit to take the banking info off my laptop in the middle of the night without me knowing it. A Purism laptop doesn't protect me from the smart teenager any more than an HP does. Full disk encryption and a Yubikey probably does, along with a decent firewall. Using cloud services where I encrypt my data before uploading is better than one where I transmit unencrypted (or where the cloud service controls the key).
A company willing to drop several thousand dollars on a Talos II might be worried about corporate espionage, so they might be willing to pay for a verifiable bios.
The NSA has to worry about thousands of hackers from dozens of countries around the world, so they are willing to pay for custom silicon.
Of course, you also need to consider physical security, which is like this: https://xkcd.com/538/
(Of course they don't solve the problem of firmware on disk controllers or network chips, but there is no such project yet.)
Purism tries to be free, and is a step up from other vendors, but doesn't go far enough for some people.
