No company should exist at that size in a society that has a healthy distribution of power and fair competition. These businesses need to be split up ASAP. And if they aren’t, they should be heavily taxed and heavily regulated. If you’re that big and powerful, you are pretty immune to competition since you can eat losses, copy ideas from others, push your services unfairly, bundle things, etc. We need higher taxes and new anti trust laws that actually do something based on size or a lower threshold of market share, even if there’s no evidence of consumer harm. Getting bogged down in lawsuits around old toothless antitrust law is why nothing ever changes.

Also, at that size you’re basically like a government service. Companies like this should be held to standards as if they were publicly owned utilities, on topics like pricing or transparency or free speech or whatever.
