No :) The organizations I work with have SOPs in place to address
that. They would not be running an unapproved image in the first
place.

*If* the user installed a CA for interception purposes, then yes, I
would blame the platform. The user does not set organizational
policies, and its not acceptable the browser allow the secure channel
to be subverted by an externality.

I think the secret ingredient that is missing in the browser secret
sauce is a Key Usage of INTERCEPTION. This way, a user who installs a
certificate without INTERCEPTION won't be able to use it for
interception because the browser won't break a known good pinset
without it. And users who install one with INTERCEPTION will know what
they are getting. I know it sounds like Steve Bellovin's Evil Bit RFC
(Aril Fools Day RFC), but that's what the security model forces us
into because we can't differentiate between the "good" bad guys and
the "bad" guys.

In native apps (and sometimes hybrid apps), we place a control to
ensure that does not happen. We are not encumbered by the broken
security model.
