The only thing Kroenke cares about is making money. He and his wife bought the Av's and Nuggets for under $500m in 2000, and he knows he'd make a hell of a lot more than that on them now. He's probably content to sit on that.
He didn't care about the Rams in St. Louis, moved them to Los Angeles to get a few extra bucks and I doubt he is suddenly going to start caring about them in LA. Just increased the franchise value and it is easier for him to make money, even if nobody turns up to games.
The Wenger extension at Arsenal shows the level of ambition there. They keep a coach who hasn't won anything significant for well over a decade because he has typically kept them "competitive" (top 4 in EPL & Champions League knock out stages) on a smaller budget than other top teams.
This isn't a major revelation... Kroenke openly calls himself an "investor" in teams, which should make it clear he doesn't have any emotional attachment in their success or failure, only about the return.
