Here's the thing, though. This isn't isolated. Disney has been playing super-hard ball with theatrical distribution for a few years now, pretty much since The Avengers. There are tons of articles about it out there. They are putting the enormous squeeze on the theaters in unprecedented ways (both financial and contractually in lock-ups). This happens to be one of those ways when Tarantino is affected, but it's just one spoke of an ongoing strategy of domination that, if it continues, very well could lead to anti-trust issues if it keeps progressing. This is more like Taylor Swift taking on Apple Music streaming than it seems at first blush (where there are a lot of little guys that he's really speaking up for).
I'm 50/50 with Tarantino on this one, for various reasons - but the dumbest thing was to schedule ANY movie this month other than Star Wars. I think conventional Hollywood thinking would say that it was a great idea to schedule (what is presumably) an ultra-violent, black comedy with a refined pedigree, as the "counter programming" to Star Wars. The problem is, Star Wars appeals to such wide demographics that there is no counter-programming to be had. The 30-50yo male audience typical of Tarantino will be waiting for Blu-ray for his film, because they'll be going back to Star Wars multiple times.
