No, that's how words lose their meaning: when they are used in inappropriate context to describe something completely unrelated.

Another modern example of a word that rapidly loses its meaning is "fascism": these days it is used as a general term for any policy not supported by the person that uses it. BLM fascists, left fascists, ultraright fascists, antifa fascists. On the subreddit about new Apple "Foundation" show someone described the depicted Empire as fascist. Everybody are fascists, especially the US who have fascias everywhere in state imagery!

I hate what you refer to too, it's essentially changing the meaning of a word with political intent. It also happened with "tolerance", went from enduring something you don't like to not caring about it in the first place.

But all that does it make words mean different things at different points in time, which is still just how words work. The meaning of the word "gay" is pretty different now than what it was, "meat" used to refer to all solid food, not just muscle and organs, "tweeting" is, at this point, more used as a reference to an internet service than to birds.

We didn't get to learn a final and set version of our languages, we just got the current one, they all keep changing nonstop and words changing meaning is just one of the ways in which that happens.

But in our case, "piracy" has exactly same meaning as it did 400 years ago: attacks on sea vessels, plunder of wealth and kidnapping of people for ransom or for sale.

It has precisely zero relation to copyright infringement, and should not be used to denote the it.

When healthy discussion is needed wrong terms do not help because they become propaganda terms masking the real meaning. In that case they should be reconsidered and corrected for discussion to have any chance for success.
