Didn’t say “sole arbiter”.
If some yahoo files a gazillion dollar suit against you because he claims copyright on the phrase “So Pepsi, and not the courts, are the sole arbiter of what is right, and what is not?” and says you stole that phrase to his everlasting agony, will you proceed to spend several thousand dollars responding to the suit? No, you’ll blow him off.
Ditto Pepsi. A couple Yahoos from Wisconsin say selling water in a bottle was their idea and Pepsi stole it. Does Pepsi take them - and all other frivolous/trolling/harassing suits - seriously at a cost of several thousand dollars each? or just ignore the idiocy?
Not if I've been served with official docs telling me I'm being sued, and knowing that courts find for the party actually appearing and not "blowing them off", then yes, I would appear.
My point was that Pepsi does not have the right to decide what is legally correct and what is not. That is for the courts to decide.
