They're the same kind of people who made the word "liberal" mean "socialist" or "interventionist" which is something of the opposite of its original and true meaning.
But the fact is freedom has a simple and plain meaning, and it's a meaning we need to have a word for. If you want to say that police stopping you from using marijuana is good, whatever, just make up some other word for that because that's the opposite of freedom.
Or if you think people have the right to "freedom from want" at the expense of others, it's nothing but a nasty and misleading rhetorical trick to call that freedom. It may or may not be good, but you're taking away people's freedom of choice when you force them to provide for the poor. Force is not freedom, it's force, end of story.
