"Free software" and "open source" have very clear meanings in software industry. Nobody can force you to use them correctly but don't get angry or even act surprised when people complain that you are wrong and even deceitful (when the error doesn't seem naive).

If you go to a flight engineer and say that a plane has a high risk of stalling, first thing the engineer thinks would be a problem in the aerodynamics, not some engine problem, which would not make sense according to the dictionary definition: Stalling: Stop running, typically because of an overload on the engine. (Random example from the top of my head and my example can theoretically be very wrong, but I hope my point is clear).
