You have two choices for phone ecosystem, and they're both bastards about what you can put on your device. Google uses the tyranny of defaults, deeply buried settings, and scare walls to accomplish much the same thing that Apple does by strictly being draconian. It's mafia behavior over the most important device category in the world.

Both of these companies need to have their asses handed to them. Not just by the US DOJ, but by every country. What we do with our phones is bigger and more important than two companies that got there first. They'll still have their trillions dollar market caps after the DOJ tells them they must allow web installs.

Apple and Google's only role should be to provide a hermetic sandbox with permissions layer and do occasional malware scans. That's it. Once we buy the devices, they're ours, and these companies should have no say as to what innovation takes place and what customer relationships are built after the initial sales are made.
