That's fair. My personal opinion is that if he really wanted to stay, even if he wanted to wait for new ownership to sign on the dotted line, he'd be actively negotiating with Dorion.
It'd be in his best interest to make his commitment clear and have a framework of a deal in place, so when the sale goes through, Dorion can go to the new owners, convince them that signing will be money very well spent, and wrap it up quickly.
But that doesn't seem to be what's happening. Debrincat's camp has, reportedly, given Dorion the cold shoulder the entire time.
Why wait until new ownership before even talking? Doesn't make much sense, since the guy you're not talking to can easily trade you in the next 3 weeks. If you piss him off, or make him question your desire to stay, by not engaging, he doesn't need permission to send you to Calgary for a year.
And from the sounds of Dorion's press this offseason, it doesn't seem like Debrincat has said "I want to be in Ottawa". If he had, Dorion wouldn't have been as blunt about arbitration or trades.
