While it is frustrating to pay thousands of dollars for music only to have it available for free online a few weeks later, we don't really make a big attempt to stop piracy anymore. After the season, we don't really care much.
Don't want to start the discussion again, but teams do copy each others stuff during the season from videos and music. One of the teams we competed against in finals at Worlds pretty blatantly copied a pyramid they had seen done by one of teams. Copying after the season is one thing, but to use it in the same season against the very team that originated the skill is not cool in my opinion.
