He's very well loved by most and for very valid reasons, but there's some pretty interesting stories about Frank's handling of certain folks at OLTL and GH. When he freezes someone out or wants to placate them he'll allegedly say a lot and do something else. I think he can be a control freak, but he's never treated his shows with contempt in the way I feel Goutman did near the end. (The audience is another story)
But yes, I do think Martha would never have left. I've said before the vibes with her and Goutman are very strange and make me think there is a huge story there that's just barely never been told. I have never gotten vibes like that off FV with anyone, ever.
