Well, if one reads this ebuild script for ChromeOS, it clearly states that bash is only used for building ChromeOS, but dash is embedded into the built image.

Thanks again for proving my statement, "Google avoids GPLv3 like hell, if the target audience is 'big licensees'".
But you already did that before, IMO it did not need another proof.
And ChromeOS was just an example how Google handles GPLv3 software in order to understand Jolla's concerns and strategy better (which is achieved now).

WRT the GPLv3 itself:
It is only the license text which is legally binding, last but not least because this is usually the only legal text referenced by or supplied with GPLv3 software.
Demanding references to statements of the GPLv3 not to point at paragraphs within the GPLv3 does not make much sense (even if the "demanding" aspect is fully ignored).
Especially as you completely fail to reference any of your claims with something within the GPLv3 license text!
