For a recent example of this see "Red Pill", a documentary about the Men's Rights movement. They were backed via Kickstarter and promised backers a "pre-release" download. Because they wanted to be eligible for an Academy Award nomination they ended up releasing the movie in LA (and New York I think?) for the minimum run necessary and then waited another couple of months for the official release as digital download. Because of the Academy Award rules they held back the "pre-release" downloads until just before the release of the digital download version. They angered a lot of backers by saying it was still technically a pre-release because the digital download hadn't been available yet although the film had already been in cinemas and available for private screenings for months at that point. It's a good example for bad communication. Especially when upset backers were basically told the "pre-release" would happen at the last possible moment to combat file sharing, but that's another tangent.
