Nope. Not in the RSA. Two points, if I own a license to something, I can download it seventeen times over, and no one can say a thing about it. If you buy a CD, your paying for the license, not the medium the music comes on. This license entitles you to use the music, with certain restrictions, as printed on the CD.
Second, in the RSA it is only illegal to distribute copyrighted materials, i.e. uploading, or writing to a disc and selling from your boot or some such.
All that said, these t-shirts are clearly illegal. MyGaming's stance has always been anti-piracy, and while this might not be exactly what was intended when this rule was made, it's the exact same law being broken.
For what it's worth, IANAL and TINLA.
