iMessage is the most egregious monopolistic tool in Apple's garden. If the DOJ accomplishes nothing else besides forcing Apple to open up iMessage, it will be a victory. The lock-in of having functional communication with your friends and family is insane. Take that away and it becomes almost a no-brainier for people to consider competing devices.

Couldn't Apple just make the shittiest Android iMessage client anyone could ever imaging and the go "See, there it is, nobody wants it"
My take is that Apple has engineered iMessage in such a way that if anyone could just use it, then Apple would be stuck with a massive bill for running the infrastructure, without any benefits. They could in theory charge people a small amount to cover the cost, but that would also just keep people of the platform.

iMessage being Apple only isn't what keeps me from buying an Android phone (Google manages to do that all by themselves). I already have three messaging apps on my phone, and four on my laptop, there's plenty of choice on that front.
