If you purchase software, and you accept the license (usually by opening the shrinkwrap or the CD case), you are bound to all its terms. The EULA is an agreement between you and the publisher of the software. If you then go and violate the terms of the EULA, then the publisher has the right to terminate the agreement, insist you immediately cease use of the software, and demand you destroy all copies of the unlicensed software. Such is the nature of any license agreement, be it with an end-user or another business. No responsible copyright holder would waive this right in the case of the terms of the license agreement being violated.
