The short version: Dybvig left his faculty position at Indiana at the end of 2012 to join Cisco, and Cisco bought Cadence Research Systems (the company set up for licensing Chez Scheme), too. There's an FTC filing somewhere, but my Google-fu is failing me.

The $65-per-seat price was listed by a third-party Cisco vendor. There's never been any explanation as to how they came up with that price, nor whether anyone tried to purchase it that way. It was fun to tell people to get a license, especially given the normal prices (which someone else posted).

It actually predates Dybvig's time at Indiana; he started writing it as part of his PhD work at UNC Chapel Hill. Plus, he set up Cadence Research Systems for licensing Chez Scheme, so it was never owned by any university.

The part where Cisco open sourced it is a bit unusual, but it's not uncommon for people to close source and sell systems they create during college or grad school and continue to use them in research.
