Pretty sure this is "compromise" pricing to not hurt movie theaters. It's important that they not put out a cheaper option on the same day the movie debuts in theaters. Even people who intended to go to the theater will consider staying home if their whole family can watch the movie for 5 bucks at home. If you want theaters to stay alive, don't ask for a lower price this early in the release. The alternative was always not having the option to rent it digitally at all until weeks after the theatrical release. So you've been given another option. You can pretend it doesn't exist and nothing's changed by just waiting a few weeks for the price to drop.
