More data raping
Zephyr's IP stack means your Chromebook can send data to Google when you have turned it off.
Just junk the B'Stards already.
You probably knew Google's ChromeOS is a Linux distribution. But, now, it's running on more than Linux under the hood. I didn't, and I've been covering Chrome OS like paint since the day it arrived. Today, your newer Chromebook also depends on the open-source Zephyr Project Real-Time Operating System (RTOS). Here's Chrome OS's …
It's licensed under Apache 2.0. Even if it was GPL, there's no guarantee you'd get to see the real source used (all those kernel modifications from Android phones that never got released even though the licenses require it, for example). With Apache, there's not even a need to. They've pointed out why they use it: they work with so many different boards that don't use a standard firmware (thanks ARM, really appreciated) that they have to modify the source. This means that, although the core of Zephyr which I can read is almost certainly in there, the chances are good that the version to be found in the chip has received several changes and I'm never going to see the code that implements them. Those changes may just be functional, and I think it's likely that most manufacturers' are benign, but I can't prove that.
There are two kinds of Open Source licence: weak ("stealing is not sharing") and strong ("not sharing is stealing").
The Apache licence -- Google's favourite -- belongs to the former camp; and actually allows you to declare that a software product is Open Source, without ever releasing a single byte of Source Code.
"Google...really hates the idea that someone might purchase a chrome book and put a different OS on it."
As an exercise I replaced ChromeOS on an obsolete intel chromebook with coreboot, Win10 and then Ubuntu but anything that annoys alphabet has to be a bonus.
Why? It's not going to have anything close to the performance of a cheap x86 based one, no where near as good a battery life as an ARM one, and likely to be more expensive than either, despite saving a couple of cents not having to pay an IP licence.
