Yes, I can. How is it not fair to mojang? I am targeting players that already own a valid license.
You know, you're right, I'm a bloody pirate. I'm distributing the minecraft.jar to people that already own minecraft, now that's mighty unfair isn't it?
And it's so difficult for my fellow pirate brethren to get a copy of the jar elsewhere, I am the sole and single almighty source. I'm solely responsible for all those other poor saps getting everything for free. I mean, who can blame them when I make it so easy? All they have to do is download MY jar, get all the other files from elsewhere, crack the login and version protection! Child's play, really.
I should do it the same way all other mod packs do it. I should force those pirates to go elsewhere! Those hardcore pirates still won't pay for minecraft, and the soft-core pirates will find something else to get for free.
I should make things difficult for my legitimate server users just to spite those bloody pirates! Now that's customer service, and is sure to increase popularity for mods and for minecraft!
End sarcasm.
Have a nice logical day.
