Players and coaches don't have incentives to extend series to manufacture additional games... and that's a good thing for the integrity of the game.
Given that the team has gained about a half-billion dollars in valuation in just a few years, shed no tears for ownership.
For the teams, the league, and perhaps most importantly, the broadcast networks, extending series is a big potential for additional revenue. One estimate I've seen claims that ABC missed out on as much as $45 million because the 2015 Finals didn't go to seven games[2]. If David Stern, who was notorious for appearing to put his thumb on the scales, were still commissioner of the league, I'd be watching the officiating of the next two games very closely.
