Worse, no competitor should allow their employees to ever download or worse look at the source code as it would taint all their IP with possible theft. Just because the code is leaked doesn’t mean Rockstar has lost ownership of the intellectual property, it just means everyone distributing it is participating in the theft and everyone holding it is complicit. Worse by reading it and possibly using trade secrets embedded in the code in a competitors product exposes the competitor to civil and criminal penalties.

I would treat the source code as radioactive toxic waste to be handled at your own peril.

ReactOS also treated/treats leaked Windows source code this way (disallow contributions even if you have academic or goverment-backed permission to look at it).
