I think that if that was feasible a successful project would exist already to develop it. it is not like people does not want it to exist. sure, there are tons of projects making variations of existing browsers but none of them do much besides minor tweaks.
From the top of my head Servo is the closest one and it has a big head start since mozilla developed originally. and that is just an engine, not a full browser.
the current law does not allow them to no comply. they can go to court, but they would be required to comply in the meantime.
unfortunately the UK law says not complying is a criminal offense, not just an administrative un compliance. so apple employees would be liable to criminal charges.
this is very bad but it’s the draconian UK laws the problem here.
I’m conflicted on what would have been the best course of action.
if they would have fought this (in private) I assume people would assume they were complying. so the only option would have been to break UK law and fight it publicly. I am not sure that was feasible.
but this also just creates a precedent for other countries push apple to do the same
they are mixing gigabits with gigabytes so that is confusing. but even then, the math is still wrong for the usb 2 speeds.
