I had to look back at my post, because I do have a distaste for nvk, but the only thing close to an ad hominem in there is that I say he should stop shitting on seed signer (i believe I called it "whining" as well -- in another comment, I suggested that he felt Coinkite was challenged by Seedsigner, but again, I don't think that's an ad hominem).

In the land of bitcoin, the overwhelming message I hear is that "good bitcoiners use hardware signers." I think it's okay to point out that there are flaws in that approach -- just as it is helpful that you are pointing out the flaws in my approach.

I also think that my other criticisms of his article are fair. He doesn't acknowledge the supply chain, evil employee, honeypot, and man in the middle risks of hardware signers. I have tried to point out risks in Bitkey and other hardware signers as well in other posts.
