I think that this is a legitimate moral position to take, but I think you will find that it is less widely held than other legitimate moral positions you might take (for instance spy agencies spying on their own citizens is more broadly recognized as bad).

Further, it seems to be a moral position that doesn't have much basis in practice. Industrial activities are fundamentally linked with traditional espionage targets such as diplomacy, military technology and military operations. To deny an intelligence agency access to those things seems no different than to deny them the ability to operate at all. Which is another legitimate moral stand to take, but one that has even less broad acceptance.
