If you know anything about law or political science, you'll realize that "theft" relating to emulators and ROMs are soft laws (meaning, they're not written and included in a set of laws that lead and govern modern society), not hard laws. This is why you get so many contradicting statements. It's basically, "please don't use ROMs of emulators, it's stealing. However, if you do, there's not really much we can do about it." Plus the fact it's very difficult to trace ROM and emulator usage.
