At the end of the day, I think that what comes out of this is that there are many people who misunderstand Modern Orthodoxy. There are the chareidim who don’t understand what it stands for, and there are the Conservadox who can’t admit they’re leaning towards being Conservative, and are trying to hold onto the Orthodox label, who claim “I’m modern!” as a reason to do things which aren’t allowed.
The “true” Modern Orthodox, as defined by its Rabbonim, is perfectly legitimate.
