I did a little digging into it and it seems like they were doing something to the radio modules to crack into the OS to add back in or enable the CarPlay/Android Auto features in it and it apparently was... sketchy. Things like not persisting through updates, sketchy.
They also still have some quotes before White Automotive yanked their pages down.
"Servicing vehicles with this modification does require a little bit of common sense. Dealers should not service the radio module."
Also, apparently the radio module is so heavily integrated to the vehicle that removing it renders the vehicle undrivable (i.e. to send it off for modification).
