I may be wrong, but I think that in practice *all* of the tests must be considered.
Notice that test #1 specifically states "nonprofit educational purposes" rather than just "nonprofit purposes".
This would not need to be included if it was not meant to be considered together with the other rules.
And I believe that "educational purposes" are legally for the purpose of teaching others, not yourself.
I am not a lawyer. As a writer I am starting to look into copyright law.
Maybe I'm naive, but I don't believe this. The only applications on my computer are legally obtained. I do *not* illegally copy software (or anything else if possible).
I have no illegal software on any of the computers in my house to my knowledge. Neither my wife nor I would use such software anyway.
Actually both of these entities have agreed that the decoders are fine. Only the software that make such images costs money. And I have paid for such things indirectly by buying commercial graphics programs.
I might not know if a single book from my library was stolen, but it would still be theft.
Even if, as a squatter, you added value to the house (by keeping the garden flowering and repainting and such), you would still be there illegally.
No, the library has legally obtained that book. This would be like loaning a book of your's to a friend. While I have the book checked out of the library, nobody else can read it.
For some software, yes. It was accepted practice regardless of the legality for personal software. Professional software was different.
I believe that this is like lending a book. I believe that legally (unless the EUL says differently) that the origianl owner must uninstall his copy before lending to his friend, who must install it.
So everybody you knew was probably violating the law? Once clue is that if you had to use special software to copy an program, it probably is against the copyright agreement.
This is a very old argument. You *are* allowed to sell any GPL'ed software as long as you adhere to the GPL. As of my last reading, you either had to make the source available or point to where the source was.
I can sell gcc. It would be silly of somebody to buy it, but the sale would (as of my last reading of the GPL) be fully legal. Of course, my customer could then sell lots more copies, all in the name of the GPL.
This only talks about ideas, not their implementation.
