How do you "plunder" the public domain? Is there not an army of pedants out there eager to tell me that copyright infringement isn't stealing because it doesn't deprive anybody of anything? Is it not the point of the public domain that anybody can use it?
Plunder doesn't seem like the right word for that, though.
plun·der
(v) Steal goods from;
(n) The violent and dishonest acquisition of property.
I think using the public domain is a good thing. I think that describing it as "raiding" and "plundering" when someone you don't like does it is bullshit.
I don't think anyone who's using the term thinks plundering the public domain is a bad thing
Then why would you use the word plundering to describe it? That's like saying rape is part of a normal and healthy marriage. If you don't mean rape, don't call it rape.
