They make that one cake for that one kid/family. If that's illegal, it shouldn't be.
That one cake for that one kid, and another cake for another kid, and... do I really need to keep going?
The family of the birthday boy isn't intending to make a profit of someone else's idea.
No, but the bakery is making a profit -- cake by cake.
But to a kid, it can be so much more than that, and that shouldn't be ruined over silly red tape.
You are invoking "think of the children!" here -- a plea for pity that is used as an appeal to emotion, and therefore it constitutes a logical fallacy. Law doesn't care about emotions, just facts.
Ummmmm, mine would be substantially different than the paid one. There are two mario games, a paid one and a free one. I gave mine away for free. You can buy the other one if you want too and have 2 different games. Yes?
Nope.
The very existence of your game deprives the copyright owner of the opportunity to sell a similar game.
Hypothetical situation -- copyright owner pays a developer studio to make a game. It pays publishers to publish and distribute the game. It pays a marketing firm to create an ad campaign. It pays designers to design merchandise, factories to produce it, and stores to stock it. Before their game is released, you release your game which turns out to have exactly the same mechanics and it targets the same demographics as their game.
Does it matter that your game is free if they lost a ton of money, and can't recoup any of the expenses because people can just download your free game made using their IP?
No it doesn't.
Use of IP that is not at the expense of the original creator should be allowed.
The point is -- you can't possibly know what is and what isn't at their expense. See the example above.
The originality isn't in the characters, its in the intended use/message sent by the photo and what the meaning is behind it.
So go ahead and enlighten us, what is the deeper meaning behind that photo?
All I see is two copyrighted characters involved in a controversial activity which in many countries around the world is still illegal and carries a jail sentence.
So, unless you believe that just including
shock value is enough to turn something into a work of art (I don't, and that's why I never watched Game Of Thrones) that photo is worthless and devoid of any real artistic expression, deeper meaning, or hidden message.
