To quote Internet Archive's Jason Scott, "I wouldn't use a Kryoflux to pry open my last can of beans."

IA's Archive Team have guidance for anyone wanting to archive floppy disks:

and optical discs:

From the links provided, the issue is regarding documentation of the image “flux” file format and the availability of software tools to manipulate the images. Jason Scott probably doesn’t want to use a proprietary format for archival of disk images, and that’s fine. For someone to say that Kyroflux is claiming ownership of images created by its customers, however, is just misleading.
I think the answer then would be to come up with an alternative that works on approximately the same level.
