There might be a financial incentive to make hardware to crack crypto to sell to governments, which could use the hardware to spy on people. In other contexts government contractors do make surveillance hardware, like IMSI catchers. Because the crypto involved is so easy to attack, it's possible to imagine someone building a passive cell phone monitoring box with ASICs in it.

I haven't looked through the relevant stuff in the Spy Files (vendor presentations from the ISS World surveillance conference), but that might be one place to look to find people making crypto-cracking ASICs for a profit.

They only have documents through 2011, although the conference is still happening frequently.
