You are uninformed.

GPL has stand the test of courts in both US (e.g. Drew Technologies, 
Inc. v. Society of Automotive Engineers, Inc.) and EU (e.g. Welte v. 
Sitecom). The reason that GPL has not been challenged more often during 
its 18 years of existence is the fact that no one is willing to risk 
contesting it. That is, most companies realize that they will loose a 
lawsuit.  And if it is challenged, it usually ends in a settlement (e.g. 
NuSphere Corporation (Progress Software) v. MySQL AB).
