Of course EK wants to stay in Ottawa. He loves the city. His wife who's expecting their first child is from there and her family lives there. He obviously loves the Sens and is very proud of being the captain.
What he definitely does not love is ownership. I'd actually think that EK more than most players would take a hard look at ownership before making his list. Players come and go, management/coach are fired but ownership doesn't change easily.
One has to remember that this isn't the first time EK is up close and personal to Melnyk's antics. Alfie deferred salary to keep the Sens competitive with the 'gentleman's agreement' that he'd get paid fairly later on. And he was still a damned good player when his new contract was up and Melnyk reneged on the deal. Presumably then EK won't give Melnyk the benefit of the doubt, considering his recent comments, not to mention the earlier olympic ones. As for the list, he wouldn't put any of the division teams on it, since the chances that he'd be traded there are minor. Presumably he'd also put teams he's too obviously a rental for and that wouldn't have the cap space after next year to re-sign him. He'd want a team where he could stay long term.
I feel rather sorry for Dorion, who seems to be a decent GM, having to deal with Melnyk undermining him.
