The point of the post you're replying to is that you cannot simultaneously act like 'free software' has one canonical definition which the software definitely violates, while 'open source software' is the nebulous one which doesn't necessarily mean anything more than its availability in source form. If 'open source' doesn't have to mean what everyone who actually uses it means by it, then neither does 'free software'; if 'open source' can just mean source-available then 'free software' can just mean software for $0; if advertising your software as 'free' is false advertising if you're explicitly violating the FSF's definition, then advertising your software as 'open source' is false advertising if you're explicitly violating the OSI's definition.
