air-gapped or not doesn't matter

trusted operating system does.

I got no problem with the jade, the problem is most people use corporate-government (fascist) operating systems.

You can have the best air-gapped wallet out there, if you are using windows or mac, your privacy is busted by the gov simply by whats on your screen.

You can have no security without privacy.

I agree with the sentiment here.

HW is better than no HW.
