People I know who have run internet startups have had contact with federal agents on various occasions. EDIT. This response is getting so many upvotes I'm going to clarify it a bit, particularly for people who may be reading this from other countries: Yes, you can start and run a business in America without ever having direct interaction with the US Federal Government, other than mailing off your taxes. It's not like every business one day gets a visit from the KGB and they tell you to do things a certain way (or else). Nevertheless, if you are for example an ISP or provide messaging, as you grow big enough it's probably a matter of time before you'll end up getting a subscriber who's being investigated. You may have a former employee that goes on to apply for some sort of special security clearance and they follow up on his background (or you go out of your way to hire a talented hacker with a mysterious background). You may simply meet such agents due to ordinary shared interests, like say at a trade show or a conference. Of course, you could also meet them when they are also actually investigating something with the aim of prosecuting people. I don't know which of these situations fall under the law described in the article, possibly all of them do.
