CVG - Spector: Thief limitations inspired Deus Ex

I'm not sure that I understand his criticism of Thief but apparently frustrations with the game inspired Spector to do Deus Ex.  From CVG:

The exec told Xbox World 360 that he was "so frustrated by Thief" and the way it forced players into combat, that it motivated him to create a game where sneaking and fighting were both viable ways to deal with a situation.

"Deus Ex exists today because I said, 'I'm going to show these guys that I can make a game where you can sneak and fight and make it work'" said Spector.

Spector's defiance eventually extended to the purpose behind Deus Ex, which he says he created with the intention of shaming other devs.
