Warren had different beefs with Google, Apple and Amazon, but the common thread was that she accused each one of using its powerful platforms to “lock out smaller guys and newer guys,” including some that compete with Google, Apple and Amazon.

And a comment from Spotify’s Jonathan Prince:

“Apple has long used its control of iOS to squash competition in music, driving up the prices of its competitors, inappropriately forbidding us from telling our customers about lower prices, and giving itself unfair advantages across its platform through everything from the lock screen to Siri. You know there’s something wrong when Apple makes more off a Spotify subscription than it does off an Apple Music subscription and doesn’t share any of that with the music industry. They want to have their cake and eat everyone else’s too.”
