crap gamz, I'm not sure if you're familiar with any other game authoring systems or game engines, but most of them do the same as FPSC does, leave all of your data unprotected. It's a very common practise to do so. There are a few engines that do gove you the options of packing the game, but you have to pay extra for it.... quite a lot extra.
It isn't TGC's responsibility to protect your date and the didn't make any untrue claims at all. There are a number of data protecting applications for gaming engines available, but they aren't cheap.
I'm very glad FPSPack has been developped and I hope the development of it will continue with even more protection features.
