Re: Right, but do all those businesses...
I had my suspicions on that count too, but let's bear in mind that you'd likely have to put the effort (and quite possibly a lot of money) even taking it to court to get them to agree with that, if they did.
Something I suspect Oracle (and countless other manufacturers' unenforceable contracts) rely upon.
Then there's also Oracle's modus operandi of having licensing that's opaque and convoluted enough that there's always some other missed infringement they can catch you out with if you piss them off and they decide (coincidentally, cough) that they fancy auditing you. (Whether that's actually the case or not doesn't really matter so long as the customer isn't clear, and I get the impression their sales people use that as a barely-veiled threat often enough).
