I actually think reframing these issues as something that might necessitate a fork for corporates could be good for all involved because that hopefully would mean less egg on Mozilla's face when someone finds out they're being DPIed.

There's a lot more nuance than I've acknowledged, but I'd much rather people make a fairly consistent set of assumptions about the trustworthiness of Firefox and a second, different set of assumptions about corporate MITMfox.

Even though I'm not a fan of it, I also recognize that companies own their assets and need to protect their networks. But should Firefox stay completely quiet by default when an IT department MITMs an employee's traffic? Even if we all acknowledge the same IT department could turn those warnings off, I think it would still be a start.

This will always be a cat-and-mouse game and I agree that Mozilla may not be able to permanently 'win' on behalf of users, but I think browser vendors in general could do more to shift norms and change the 'framing' of whether users see (for example) a monkey-in-the-middle icon instead of a lock icon by default when they're being MITMed by adware or corporate DPI.
