I can't quite figure out what you disagree about. I stated that 1) ProtonMail Bridge makes things less secure and vulnerable 2) that I think it defeats the purpose of using ProtonMail in the first place 3) that you have to worry about the security of another software with ProtonMail Bridge.

I think you're saying that you're more likely to be compromised because of the host, and this is where I'm confused, because I didn't claim that you're more likely to be compromised by someone having access to your machine.
