Interesting discussion. Satellite appears to be facing the same dilemma that OTA radio faces, except OTA radio is free, and satellite is not. And everybody loves the cost of free.
Once satellite radio becomes primarily internet stream based, and less based on the actual satellite, they will be just another internet content delivery service, competing with every other content streaming service out there, including thousands of FM and AM radio stations which have streams.
They may have an app, but it's one out of a gazillion audio content delivery apps. In other words, tons more competition for ears in the car. In 2005 it was OTA, satellite radio, or your CD/Cassette deck. Now it's bazillions of streaming services, OTA, satellite radio, and maybe some holdouts using bluetooth to play their Katy Perry MP3s, and a handful who still play CDs in their 2000 Kia.
