Leaked Versions

Why do people make leaked versions of things ? im just curious.

Not everyone cant afford certain things or just dont want to pay for it(mostly kids) so they get greedy and often look for stuff for free(i aint acting like i dont do this) and people on forums like these like gaining their resource count or like getting more credits so they can get leaks themselves or just contribute to the site for any reason or the other it all circles back to providing leaks for leaks.
