App stores are under fire, but they might be necessary

A recent Senate antitrust hearing focused on smartphone app stores and the fees Apple and Google charge developers: 15% for small developers, 30% for larger ones. Match and Spotify said the fees were too high for what Apple provides and that the terms can change without warning. Companies also pointed out that sometimes Apple might make apps that compete with external developers' apps, as is the case with Spotify and Tile.
