But it's so, so far ahead of iOS in openness. You can sideload apps. You can spin up Android in a VM. You can buy Android devices with unlocked bootloaders and install your own roms or drivers or kernel modules or whatever else. The system can be made yours to command.

iOS doesn't even let me run my own code in userland.

This has been possible for a long time. Yes, there are some hoops to jump through (7 day time limit per signing unless you pay), but to say it doesn’t allow you to run your own code is just wrong.

Limited userland code.

What code do you want to run that you can’t in any way? How is running that more important than the alternative?

Code that can generate new executable pages on the fly, code that can access the various databases on my phone, code that modifies how the system applications work…I think that's fairly important and useful, especially since the alternative is…you can't do that at all? What's the issue?

That's somewhat tangential to the item at hand isn't it? We are talking about open source, not about hackability or the rather vague term of 'openness'. One could argue that a device that is usable to a lot of people is 'open' and devices that all require their own teaching/learning are not.
