Sleazy, sleazy, sleazy. 20,000 hours is ten man-years. There's no way they did that. This is tantamount to theft of open source code.

This needs way more attention than it's getting right now. Ripping off the hard work of the FOSS community and then commercializing and privatizing the results is wrong.

This sort of abusive behavior is exactly why projects go closed-source, to the detriment of all mankind. Shame on them.

Tar and feather is my suggestion.

Also, if I recall, doesn't some of the hardware licensing track back to the TAPR OHL?

Don't know if it's TAPR or GNU open hardware, but one of those. Aside from the persistent comm's problems with Apache, they've always provided schematics on request in order to honor the derivative works status of the hardware they produce. Indeed, if you look at the original Hermes, Alex and Munin schematics on openhpsdr.org and compare them to any Apache schematic they differ only slightly. It's really just a question of scale (more ADCs, more BPFs, larger FPGAs, etc.) and subtle improvements.

The one thing that Apache has not provided are the Gerbers for the PCBs. IIRC, there was some controversy about this associated with the Apache RF and SDR boards in the ANAN-100D. Apache's stance was that the while the electrical schematic was not proprietary, the board layout was.

Haven't been through it yet, but their Startup Guide is attached. Checking for source disclosure/license attribution.

It appears they claim the software OL Master is GNU GPL v2/v3, but that the hardware is 100% proprietary. Very interesting. Someone more knowledgeable than me can chime in.

The section regarding “Software license” is also interesting.
