When WatchOS 5 arrives this fall, it will only work with Apple Watch Series 1 or later. That means a group of users won't get the update: those who shelled out $10,000 for the gold Apple Watch Edition.
Hey, a similar thing happened in Netherlands where suddenly a group of parents had to pay back a year worth of subsidies, which made some families sell their car, their house, breakup,etc. Still no compensation.
