Yay, another fine example of delusional entitlement. This time we've got a million dollar amusement park that puts out a call to action for artists to contribute their mask designs, and enter for a chance to "win" having their designs being used. So, basically put all that time and energy in to create a cool mask design, and have it stolen for mass distribution while the very folks stealing it from you are "rewarding" you with "exposure." They value the artists, just not enough to pay them.
