good point, but may not be relevant...
the EULA can only cover the products sold and used by the customer, not any other tools used to decompile a compiled program produced from their product - hmmm.. not sure i'm being clear enough here...
e.g. let say...
1. TGC sells DBP, USER1 buys DBP from TGC and must abide by DPB EULA
2. USER1 creates program APP
3. XYZ (external company) sells DEC (decompiler) which can decompile APP
I don't believe that TCG can apply their DBP EULA to stop USER1 from using DEC on APP, particularly if DEC was used by USER2 instead of USER1, who didn't even buy DBP from TCG and so cannot be bound by any EULA for that product. (Leaving aside the fact that it would be illegal - assuming that USER1 has stated in their own EULA for APP that this is the case).
The point I'm trying to get across is that TGC's DBP EULA cannot apply to APP that USER1 created, only to DBP.
I know that out there in the big bad internet there are lots of tools that does this type of thing, one being e.g. CheatEngine, but that is still legally able to be obtained and used (for own creations at least) and the creators of that tool haven't been locked away.
