Why are pepole selling audacity on ebay?

I got an ad on FB that took me to ebay where someone is selling this free program that anyone can download. I’m not silly enough to pay for what I know is open-source just thought I’d bring this to light.

Sadly there are a lot of economic parasites in this world that contribute nothing and take whatever they can.

That’s annoying they can get away with this. I love the o open source community and all the projects that are out their.
