As a $ZEC holder, I’m for the BOSL license on Orchard.
Initially licensing Halo2 as BOSL seems to have helped create leverage for a partnership with Filecoin and now Halo2 is set to be MIT licensed anyway. That’s where the core cryptography of this next release lives so the best cryptographers in the world have no problem working on Halo2.
This approach seems like an innovative way to capture distribution of the latest technology release that the Zcash development team has been working on for 2+ years, while at the same time making it open-source.
