Thanks for sharing this criticism. Its valid.
I am well aware of the criticisms you mention. I wanted to stick to the arguments he makes or should be making vs criticizing business decisions. You make valid points. I've heard his side of it. I would probably go a different direction if I were him, but I'm not.
SeedSigner has a very different target audience. I wish it was promoted more but it doesn't have a for profit company behind it. I honestly think this is a strength especially from state attack. Projects like SeedSigner are a big reason I'm bullish on bitcoin. Not that I believe we have to have signing devices but because they are very censorship resistant.
