Android is based on copyleft code and it is far from an open hackable system. On some devices it possible to install an own build but it requires skills and patience so not an option even for most IT professionals. But for most devices there are locked loaders and closed drivers/firmware. I don’t see a copyleft license helping if a business is not willing to participate in open-source.
