/"If people didn't pirate stuff, we wouldn't have so much DRM as
we have."/
You are confused about piracy because the companies with unethical
minds have used the media to spread the message that you are a criminal
if you share you are a criminal.
When a person is buying a software, the person should own the software
but that doesn't happen.
It is only and only like the person is renting the software from those
companies to get a job done now with proprietary software.
Let's presume a company sells a free operating system, Trisquel and
a copies of Trisquel shipment is en-route to distributors but some
people attack that shipment, steal Trisquel's copies and sell it.
That would be piracy!
