As a network engineer, I always knew when skype was misbehaving because those users always came up to me and complained. They complained because our corporate firewalls blocked them for using thousands and thousands of TCP connections when they became supernodes. They asked "how do we fix this" and sadly the answer was generally (if you were on a mac), you don't, just shutdown your client when you're not using it and it won't become a supernode. It wouldn't really have been a big deal if it was 5-10 connections, but it wasn't so it became a problem. I assume eliminating the crypto has to do with eliminating overhead, but it could have to do with DPI and making it more firewall friendly.
