Ah, I see the correction now. But spell check normally happens before you post.
So Linux is a copy of Linux. So what. Most things in computing are copies of something else. Even those few beloved (of you) BSD guys talking about removing GPL software from FreeBSD are talking about copying the GPL utilities. But you won't slam those as copies once they're done (and the copies they already have are admittedly inferior).
So everything that's a copy is bad? How about American copies. Even that wholly American icon M&Ms itself is a copy, brought to the US by someone who saw foreign soldiers eating them in WWI. This British candy is known everywhere else in the world as Smarties.
Whoops, copy of UNIX, you know what I meant. But at least it was spelled right.
