my actual example is the CTO (no background in software)
You seem to be very dismissive of people when they opine outside of where you think they are qualified to have opinions, and yet you give opinions where you might not have sufficient perspective.
Moving from linux to android for an embedded product means you basically have to rewrite absolutely everything...
Great, that is information the CTO needs to know.
for a stack that is under the control of a single company, and is rarely used outside of mobile devices and automotive.
Here the CTO has more perspective then you do. Is the company about to sign a partnership with an Android shop? Is the company contemplating moving into a new product area? Yes, the ultimate problem would not have been fixed by moving to Android, but that does not make your opinion somehow factually right. Before reacting, try assuming the person making suggestions has valid reasons for making them and try to figure out what those reasons are.
