Free TV! Gotta Be Illegal, Right?

This Wall Street Journal article is inspiring some mockery on Twitter:

Dan Sisco has discovered a technology that allows him to access half a dozen major TV channels, completely free. “I was just kind of surprised that this is technology that exists,” says Mr. Sisco, 28 years old. “It’s been awesome. It doesn’t log out and it doesn’t skip.”…The antenna is mounting a quiet comeback, propelled by a generation that never knew life before cable television, and who primarily watch Netflix , Hulu and HBO via the internet.

Ha ha. Stupid millennials don’t know about TV antennas. But wait:

Carlos Villalobos, 21, who was selling tube-shaped digital antennas at a swap meet in San Diego recently, says customers often ask if his $20 to $25 products are legal. “They don’t trust me when I say that these are actually free local channels,” he says.

Earlier this year, he got an earful from a woman who didn’t get it. “She was mad,” he recalls. “She says, ‘No, you can’t live in America for free, what are you talking about?’”

This is…a totally sensible response. What are the odds that TV stations would allow you to watch their shows for free? I mean, come on. This isn’t communist Canada or something. It’s gotta be illegal, right?
