This article on PC World asks if Purism's goals for the Librem open-source-top-to-bottom laptop are even possible. The early conclusion seems to be "No", although there's a more nuanced discussion if you click through to the article.
Personally, I suspect that it's going to be very difficult without someone reverse engineering a number of pieces of the system, or someone coming up with a fully open-source, yet x86_64-compatible, CPU design - both of which seem unlikely in today's world.
What do Soylentils think of Purism and the chances of them succeeding at Librem's goals?

Well, the page only talks about Intel (because that's what Purism uses). While I'd not be surprised if AMD has the same problems, you cannot conclude that from that page.
The Tao of math: The numbers you can count are not the real numbers.
