You can't blame people for wanting the source, and expressing their opinion.
Also, the GNU license issue was never addressed.
The author answered these questions on the previous page, what else is there to address?
The GPL license terms do not allow "preparing the code", they require the
exact code used to compile the binary be available
at the same time as the binary*.
Note that while copyright holders are not required to wait 30 days to see if the infringer cures his non-compliance before issuing DMCA/takedowns, I personally feel some patience is appropriate.
* It permits reasonable shipping and handling delays, but this is n/a online.
Anyone know yet if the "preparing the code" also included any secret malware? Did whoever reverse engineered it see if there was any bad sources in the code??
