Cock-up or conspiracy?
I know conspiracy theories are great, but this looks more like a mistake in releasing the code with the license that was used with customers who were doing pre-release, under NDA, testing, than a real attempt to prevent benchmarks.
I know Intel can be stupid, but the lesser stupidity (releasing code with the wrong license) seems more likely to me than the larger one ("no benchmarks allowed").
Maybe you can find the Intel release engineer and sign them up for your "On Call" series!
