IMO integration will force us stuck in a point of local optimum, Apple,Tesla,Microsoft,Google will decide what this point is and you will have to like it, changing a wallpaper will need to be approved, starting an application will be also approved and logged, social media apps or groups will also be censored to protect you. You will not be able to tweak a color or replace the shitty browser with a better one (Microsoft would have loved to have Apple privileges and force all it's users to use IE).

If you don't like regulators deviding, maybe we should ask users ?
