We can’t expect Zcash to be the reserve currency or the native internet money if ECC (or any single centralized entity) is the gatekeeper on dev (by way of licensing). It just will not work.
I also agree with @secparam that this topic will take up unnecessary time, energy, talent, and resources. For example, core engineers at ECC and ZF having to take time to make their personal views (support for MIT) known on this thread just seems silly to me.
Let builders build and increase productivity/collaboration to be the best use case and implementation of halo2. There’s a delicate balance between competition and collaboration… but closing the doors and having a gatekeeper will stifle progress in the space imho and put another bad taste in folks mouths.
