they never changed the moviepass model. They had a "limited time deal" of 4 movies a month 2 weeks before avengers to stop the losses that a billion dollar franchise is going to cause, and it saved them a ton of money. Once most people already saw avengers they ended the limited time deal. It was always advertised as a limited plan and that unlimited would be back. Nothing changed.
Why would HMNY run? They brought back unlimited on May 2nd, 5 days ago, that's old news.
