To me, those quotes sums up the situation.
ERIC DUHATSCHEK, The Athletic :
"Carolina’s not going to love the term because five years walks Aho right into unrestricted free agency. Moreover, Dundon’s pocketbook is going to be lightened to the tune of over $20 million within the calendar year, which is going to sting in the short term. But the draft choice compensation is so limited at the salary threshold where Aho signed – just a first-, a second- and a third-round pick going Carolina’s way if they fail to match – that the Hurricanes cannot possibly walk away from someone who is their best player and only going to get better."
SCOTT BURNSIDE, The Athletic :
"Worse for the Habs, it takes them out of tendering another offer sheet for a similar tier player (one that might actually work) and likely severely limits their ability to add other free agents in the interim on the off chance that the Canes walk away from their young star. As for other NHL GMs somehow taking their cues from the Bergevin gambit, all this would seem to reinforce is that, unless you are really and truly all-in, you’d be better served lighting the coals and getting down to some serious barbecuing before Canada Day wastes away."
It now remains a question of Dundon’s pocketbook. His decision might be made, but he'll take the full 7 days to surely match the offer. It means that Bergevin can't do any moves before those 7 days : he'll miss opportunities.
tl;dr : bad move unless Bergevin wasn't planning anything
