Did they lose their positions? I haven't read anything indicating that, just that they weren't allowed back into the conference.

They never lost their jobs. They were banned from the conference which is something hard to put a damage number on. They probably won't sue the org because they remain part of it and are unlikely to want to take any real money from it that can otherwise continue going to helping diabetes research and advocacy. Maybe they can get a future conference paid for. They're all relatively established in their careers.
