“Disclaimer: I based this piece on the current blog posts on Bitkey's website. It's possible that the final Bitkey product may differ from what is documented on the website. Furthermore, as cofounder and CEO of Foundation, I am heavily biased.” 

 So the best example of an "assumption" you can give is the guy trusting Bitkey's own claims about their own product, which is also the guy's own best example of an assumption? That's your critique?
