Have tech companies gotten so big that it's bad for the economy?

Senator Elizabeth Warren says so. She's proposing to break up not one, but several tech giants, including Amazon, Apple, Facebook and Google. She says they shouldn't be allowed to both run distributor platforms and compete on them. It's like being an umpire and a team owner at the same time.

Spotify co-founder and CEO Daniel Ek is not calling for a breakup, but he is calling for an overhaul – specifically when it comes to Apple. He's pointing to the same issue Warren is: Apple is charging Spotify to operate on its App Store, but then also competing with Spotify in the same store.

So. Is there a problem here? Should big tech be broken up? If not, should regulators step in to change the rules?
