Typical story of how the man operates.
Yes it worked this time, but the guy has a nasty habit of turning into a giant baby and saying "we're going to do it or else" when someone tells him no, no matter the fact that it's a bad idea. This entire story reads like a child saying "I'm going to do it anyway whether you like it or not" and it mentions but conveniently glosses over all the data privacy laws that were broken in doing this. Just another day in the life of fElon Musk...
BTW, this kind of "I know it all" attitude from someone who does things like blow up a launchpad(in a protected area) and rocket rushing to launch a rocket on 4/20 when EVERYONE inside and outside who understands anything about this considered it an entirely predicable outcome. This is coming from someone who has repeadedly lied about self-driving capabilities of his vehicles continues to miss the promised timeline by, what is it, 5 years now? and far from making it work continues crippling the vehicles(even removing hardware in older ones when in for service, and disabling for everything via software update) like ultrasonic and LIDAR that is widely considered to be the way forward to achieve any semblance of self driving. No, man-child decided it's going to only work with cameras, so despite insistence otherwise that's how it's going to happen(or rather not happen given his track record in this area).
BTW, this man-child is often compared to Steve Jobs. I'm sure Steve Jobs was not a particularly pleasant person to work for, and I wouldn't have wanted to. With that said, rarely did 97-2012 Steve Jobs Apple announce a product that wasn't essentially ready to go and actually did everything that it claimed to do. That corporate culture is still around. If something isn't announced "shipping today" normally the timeline is something like "shipping in 2 weeks" or "shipping in a month" and they actually hold that. A few Steve Jobs obsessive design failures like the Cube did actually make it to production(BTW, the engineers snuck a fan mount in the bottom of it because they knew passive cooling woudn't work if they moved anywhere beyond the initial shipping configurations), but for the most part he was at least smart enough to listen to his engineers(note-Elon Musk is NOT an engineer, despite fancying himself one) who knew the stuff and could be convinced that something was a bad idea and not do it. There have been a few "bad" Apple products over the years, but it's few and far between, and even big things like the iPhone 4 antenna issue they managed an immediate fix(free cases). I see little resemblance between them, to be honest.
If the cult of personality around man-child Musk didn't exist, the man would not be successful...
