GPL violates the United States Constitution and U.S. copyright and patent laws

McBride of SCO: "In the letter he said the Lindon, Utah-based SCO asserts that the GPL, under which Linux is distributed, violates the United States Constitution and U.S. copyright and patent laws. "We believe that adoption and use of the GPL by significant parts of the software industry was a mistake." "The positions of the Free Software Foundation and Red Hat [Inc.] against proprietary software are ill-founded and are contrary to our system of copyright and patent laws. We believe that responsible corporations throughout the IT industry have advocated use of the GPL without full analysis of its long-term detriment to our economy," he said.

"We are confident that these corporations will ultimately reverse support for the GPL, and will pursue a more responsible direction," McBride said in the letter."
