A company I worked at bought Firewire driver code from them (this was 15-20 years ago). The code was really, really terrible and we eventually had to replace it with our own code (which was 20x shorter, faster, and more spec compliant).

In retrospect, and as much as we in engineering hated their code, it was probably worth what they paid for it just because it got us 75% there and took pressure off the team while we created the replacement code.
