I also don't think closed source is going to work for any software where you can't aggressively prevent the user from introspecting a large chunk of the software, because it's so easy to point an agent at the tool and tell it to copy the functionality you actually care about and/or wrap it.

that is not what orthogonal means

I may be crazy but I've heard and used "orthogonal" in that context. Or I totally misunderstood the original sentence.

Quick googled definition option: "Very different or unrelated; sharply divergent."

THanks! English is not my first language.

"closing the harness is antiparallel to what users want."
