You know as well as I do that no company will ever do that. The result will be that there will be no new platforms that aren't either fully locked down or built by and for FOSS enthusiasts.
Heck, just look at WordPress for an example of what happens when a company tries to create a purely open platform and then still be a for-profit company. You can have open platforms maintained out of altruism or closed platforms maintained for profit. Android was a middle path that has now been shown to be illegal.
