But that repository doesn't have any FOSS license. Only I can find is "EULA.txt" which contains stuff like:

> (c) Prohibition on Reverse Engineering, Decompilation, and Disassembly. You may not reverse engineer, decompile, or disassemble the SOFTWARE PRODUCT, except and only to the extent that such activity is expressly permitted by applicable law notwithstanding this limitation.

And more. Doesn't seem FOSS, more like "readable source" or similar.
