c) the roll-out was nowhere near as complete as Elon's tweets made it sound it would be and a lot of people are still involuntarily on v6.2
If the roll-out wasn't to all owners, wouldn't we see a lot of whining/complaining posts from owners who didn't receive the update? (I'm talking about new whining/complaining posts created since the roll-out started.) I don't think I've seen anybody complain that they are still waiting for it...but I haven't read every thread.
