I often wonder if their content is original or if they just scrape it from other sites.

I agree. It doesn't make sense that the court would say that the government can't be sued as the ruling without looking into the actual merits of the case. Many court rulings I have seen have been more thorough than that.

Typically any work done for an employer belongs to that employer whether or not you do it on the clock or off. To me it seems that the Air Force could sue this guy for intellectual property theft because they have actually have the rights to the software that the guy wrote. The case seems clearcut to me.
