Maybe they should just come up with a model that doesn't decrease the revenue of those that create the product just so they can loose money, and make something for nothing consumers happy. I wonder how Spotify supporters would feel if an outside force decided to use your industry to destroy profits for everyone else while not even making one themselves and their salary was cut to make up the difference.
I think Apple could solve this problem once and for all. Subsidize all ebooks for 99¢ Then offer Apple music for free for 5 years. With unlimited downloads and no adds and market thr hell out of both. Suck all the air out of the room then end the trial and charge what they want. Similar to Amazon just on music too.
Keep in mind, both of these companies owe much of thier success to iOS and with Fitbit, Apple actually promoting thier product in commercials, online, and in thier stores. Many other fitness brands could never gain traction. Bite the hand the feeds you and you could eventually go hungry.
