I still don’t think the analogy captures the reality of the situation. I’d argue it’s more like buying a car that advertised room for five passengers, but when it’s delivered your discover a third row giving you enough room for your entire family of seven. Until you take it in for an oil change, when they lock your kids in the trunk and try to sell you an SUV.

There's an underlying assumption that btrfs support on those devices was actually production level stable and ready for use.

(I know btrfs on ARM wasn't really all that great at times.)
