Within that context, what's confusing you? And where did I argue that "quoting Revlon is sufficient to excuse the practical differences between public and PE companies?"
Revlon duties are a specialised duty that apply in certain circumstances. They don't in others. The other situation is what we were talking about; herego, those special duties don't apply to the other situation, which is part of the general situation. It's an old piece of rhetoric [1].
If you're consistently getting downvoted in a thread, and the other side getting upvoted, try re-reading it instead of presuming sanctity. Especially if you haven't worked in a field, are mixing up terminal and are e.g. citing legal argument about a private company to make arguments about a public one (Ford).
