That would depend on the exact wording of the EULA... And whether a
judge would find the invoked clauses binding. It is best to avoid being
dependent on a judge's judgement.

The "demo" version is a copyrighted work in itself. License compliance
issues in the demo version can be used as crowbar to achieve compliance
in the "full" version. It you play the game properly, you can even force
compliance for ALL products of the company.
N.B. If there is a click-through agreement before you can download the
demo version, it is likely binding on you.

Good decision!
