You might be right about that, but federal courts can consider state laws. I'm not sure how that would play out.
I also found an unpublished opinion from SCO Group, Inc. v. Novell, Inc., that deals with a similar issue that also makes me think that this software license could work:
> The license in the APA and the TLA does not preclude
Novell from pursing its business. Rather, the license merely
restricts Novell's ability to use SCO's property and is part
of an ongoing relationship between the parties. Therefore,
the court finds that there is no restraint on trade and the
restrictions are not void under Section 16600.
