    the part that we’re arguing against isn’t that a microsoft signing key would have fixed the problem, it’s

    I didn’t say a Microsoft signing key is required. Im saying Microsoft requires that you go out and obtain a signed certificate that proves your identity as a developer.

    this update mechanism already exists: it’s the reason the hijack was possible. whatever the technical process behind the scenes is irrelevant… that is how it currently works; it’s not a “what if”

    The update mechanism was successful hijacked because integrity checks and authentication checks were not properly in place. Notepad++ even said that they moved hosting providers after this happened to them.

    Per https://www.rapid7.com/blog/post/tr-chrysalis-backdoor-dive-into-lotus-blossoms-toolkit/

    adding signing into that existing process without any 3rd party involvement is both free, and very very easy

    Can you point out an existing open source application that runs on Windows that only uses GPG signatures?
