This. The phrase "intellectual property" is an attempt to confuse a censorship strategy that's a few hundred years old with an entirely separate tradition that's been with us for millennia. They're very different, whatever words you use for them.
Reminds of a recent discussion seen here about 'identity theft'. Another blame-shifting concept ...
And then you have the people who say that language changes based on usage. Get enough people calling it property, theft, stealing, irregardless, etc. and then you can change the dictionary.
Which is why it's necessary to point out the mistake. If we don't act now, it'll eventually cease to be a mistake.
