Not quite. As I understand it, the hardware rips disks and encodes them in proprietary SPS flux image formats (.IPF, .STREAM, and .DRAFT) subject to a very weird license agreement.[1] SPS does not assert ownership of the encoded content but does assert that content encoded with their software can not be used for commercial purposes. I suspect this “bit coloring” is at the root of why the Internet Archive made the decision to no longer accept Kryoflux based images and why it is not a good candidate for archival purposes.

It's a shame they're doing this.
But at least, there is hope that fully OSS+OSHW solutions will effectively replace it.
What they're doing is certainly not magic. Warpers existed in the 90s already.
