The folks whose data was collected were broadcasting unencrypted data over public radio waves. To assert privacy in this situation would be a ludicrous as expecting a converstion on a CB radio to be private. Or showing home movies on a screen in your front yard and then getting mad because people in cars driving by looked at them.
In a left handed way, a public service was done in that a lot of people got their first education about security and wifi routers by reading about this so-called scandal. I’ll bet more wifi passwords were set as a result of this flap than for any other single cause.
