COMPETITION OR MONOPOLI?

yeah... yeah.. ait globall theme right now.. (heiiiii,,,,what happen to me :p)
well let's see do all of u ever see the criteria or requirements from one competition, blog/ design/ logo/ photo/ story/ software making competition?!!! let's see almost have a common requirements that say
"semua hasil yang masuk menjadi hak miliki paitia kompetisi" in english "All the participant's entries belong to people/organization which held the competition"

hmmm let us think... it's fair or unfair, is it kind of monopoli or something?? why would we work hard for that? what if our creation becomes used in the next uncertain time? then we acknowledge we are not paid for that?
is it worthed??
