I'm not opposing people calling that software free.

I'm saying that you are wrong (and an asshole) every single time you correct someone calling any software without a price tag free. Because that definition is also correct, long before some deluded douche tried to lay exclusive claim to it. The "free software can only mean open source" people are the ones ignoring what the word actually means (and has always meant) in the real world. They're trying to own language and take away correct usages to service their own agendas.

Free software meant "no charge" before he pulled that nonsense ideological claim to the word. It meant it after he tried to own the word. And it still means it today. Multiple uses of the same word are fine. Trying to invalidate correct usage is not.
