It tends to be a problem with sensors that work at or near native resolution. The BMCC sensor is only 2.5 megapixels and as a result has no downsampling approach to dealing with moire. At that low resolution, they decided not to use an OLPF because it would lose them their sharpness. With a bayer pattern sensor the grid of photosites tends to cause false color artifacts, which are hard to suppress...but Canon and Sony have learned how to do so quite well. Not so Blackmagic.
Blackmagic has a camera in development that shoots 4K video and is Super 35 sized. However the inexpensive sensor they chose for that is not particularly great at dynamic range. The core ergonomic problems of the BMCC design have also not been addressed in that camera. They have a pocket camera coming out that competes with the GH3 but has the same problems as their current sensor.
What Blackmagic is extremely good at is internet marketing. Not cameras.
