Whoa, this medical device is spying on me. In my sleep. So my insurer can deny me coverage.

That’s the rude awakening Eric Umansky got when he called the company that provided his CPAP machine — a device that helps him breathe at night.

He got mad. And he got even, in a way: Eric is an editor at the non-profit newsroom ProPublica, and he tipped a colleague —Marshall Allen, who covers health care there.

The two of them together, in this episode, are hilarious and enlightening.

The story Marshall wrote opened up bigger issues about how insurance companies are collecting all kinds of data to use against us.

And it included at least one example of how the “little guy” can fight back sometimes, and win.

Extra fun: One of those examples features a 16 year-old Marshall Allen.

Note: Eric curses a couple of times. We left it in.
