Making something free doesn't really get them out of the copyright hot water, so to speak---but this change doesn't surprise me. I think the cheer community has gotten away with the use of music without approval for quite a while now and it was only a matter of time before others caught on. In the days of viral videos, all it takes is one or two of those videos from World's to hit someone who knows someone who knows someone to be like "Wait, what music are they using?" Kinda like how Abby Lee Miller is in hot water not because the courts got smart and went behind her to verify her records; but because one night the judge was channeling surfing and found her show.
