Saying something is illegal under the CFAA isn't really a stretch, it's one of the broadest statutes ever written. If you have an employee handbook at your job right now and are using the internet for your own entertainment you may be violating the CFAA.

The interesting question is are you violating the CFAA in a way that will cause the executive branch to exercise their discretion to prosecute, and moreso, is the CFAA even constitutional.
