@SuperDicq@Suiseiseki@roboneko running non-OEM software is the unlawful part in many american jurisdictions. convince the OEM to run linux-xanmod-rt and it would be no different from the windows CE it currently runs.
as for why it's unlawful, "emissions", which is the single biggest bullshit excuse i've ever heard, but folks can't say that without getting "you just hate the environment" in response.
