Sony is actually a leader in the professional camera industry.

And what happens when people go and talk to men who started out in the tech pipeline but left? Don’t they say similarly negative things?

Elon Musk is either trolling (most of the time) or tweeting while upset (e.g. name-calling a British diver -- who initially randomly insulted Musk, telling him to shove his submarine when he was just trying to help), either way you can see some sense behind his actions, even if they're puerile or mistaken.

On the other hand, Jack Ma seemed to very confidently say and dismiss a lot of things without evidence.

While this doesn't take away from your point, I'd just like to mention that Vernon Unsworth isn't actually one of the two British divers who saved the kids (contrary to what the media seems to be implying). He is just one of the many divers who tried to save them.

Also, the diver was unnecessarily aggressive and condescending toward Elon Musk (who was just trying to build a submarine to save the kids), which is what actually prompted Elon to insult him.

Amazing! Thank you for your comment.
