That has nothing to do with free software. If you have the ability to flash software then the current software on the system does not matter. Ford could make their software open source, free and anyone could download it, but it would be useless unless Ford provided a way to flash that software. The freeness of the software literally has nothing to do with this post at all.
Yea and of ford did provide the software publicly even without a way to flash it, some nerd would find it much easier to reverse engineer the flashing mechanism.
On Android you could flash new rom using twrp or fastboot. On pcs you can do similar by tapping F12.
(and obvi there should be a basic mode in case the update fails)
