It's a post that talks about the specifics of what a contract defines as a 'sale' and a 'licensing' vs what OP personally defines a 'sale' and a 'licencing' to mean, without actually sharing how the contract defines 'sale' and 'licencing' (which will be explicitly defined in a definitions section).

But IMO because there isn't that much substance there, this idea that a 'sale' might have different definitions is referred to as a 'quantum state' rather than sharing the actual definition of 'sale' used whatever contract they are referencing.
