That phrasing struck me as oddly limp. They would have been “fine” for their president to stay At his job? That’s not exactly a strong statement of support. If my boss told me they’d be “fine” if I stayed at my job I’d be pretty worried.

You're overanalysing something that wasn't the actual word used, and is an accurate word. We might all be a bit used to hyperbole, but the lack of it doesn't imply anything. Stop reading into it.

Indeed, and consider that pg is British. Not all nations share the American need for hyperbole. Some even look down on it.

If my boss told me he was "fine with me staying at my job", I'd take it to mean that they were fine with me staying at my job.

It's also the kind of thing you'd say if you knew that their heart isn't in it.

I don't think this press release (is it that?) does a very good job of dispelling the rumors that it wasn't entirely mutual, though. He ought to have said something like "delighted to have him stay".

Yeah I agree with this. And you probably know when it's time to move on for one reason or another

That is the exact scenario covered in the post you are replying to.
