The SmartScreen stuff is a plague that applies to all software developers in varying degrees. Chrome does this with their safe browsing stuff too, I hate it - essentially everyone gets told your exe is "malicious" until enough people have downloaded it without it being flagged as malware.

The idea that it applies to trusted vendors like Mozilla shipping code-signed executables is bonkers to me.

Nice way to promote further centralization into services like app stores that don't suffer from this!
