I'm waiting for him to pivot to Tesla soon going bankrupt. This is a sad script I've seen play out over and over again. Just about every single time, it is just FUD.
Tesla has plenty of problems, but bricking thousands of cars on OTA update isn't one of them. I've had my Model 3 since Dec 2018 and have done plenty of updates. One of them did brick my car, but it turned out to be a fault in the 12V battery. They had it fixed in no time directly in my garage. I was blown away by their service although it did take them several weeks to get the seatbelt tensioners when someone hit me head on. They've supposedly fixed that since, but I dunno.
These are not unlike growing pains in a service that is in hyper growth mode. You'll find problems like this, address them, and continue on.
