Can that library be rebuilt in a reproducible manner? If so, what's the difference between the library hosted by Cisco and a locally built one that is identical bit-for-bit? Is there any mechanism to ensure that the library was genuinely downloaded from Cisco rather than procured through alternative channels? If the Cisco server is turned off tomorrow, how can one tell if a copy of the library wasn't downloaded from the Cisco server while it was available?

I'm most likely missing a lot of crucial context, but it appears to me that this peculiar licensing scheme was a compromise made between lawyers that makes little practical sense on a technical level. That, or I'm far too chaotic for such nonsense.
