There's being a Tesla apologist, and then there's common sense.
The moment that Autopilot HW3.0 was detected publicly in 2018, the same thing happened. We saw dozens of vehicle owners flood service centers asking when they could upgrade their Model 3/Ys and were either given the cold shoulder or told they'd have to pay out of pocket. Many were told it would be $4-5K R&R, so most refused and went to Twitter like you did, barking at every soul alive about foul play.
Despite everyone's best attempts to reassure those complaining, as with you, most ignored common sense and believed they would be made an example of and go without what was promised. It would only be a couple of weeks later when Elon
finally tweeted, stating, "Will be done free of charge for those who ordered full self-driving."
History repeats itself. You've chosen to
ignore literal Tesla employees who replied to your tweet
asking you to give it time and to wait for a bulletin and dismissed their contributions to the conversation. You're being blamed for getting $2,000 R&R quotes because nobody, whether Tesla or Elon, has publicly stated, "go and bother your service center for this" yet. Tesla notoriously has poor internal communication; it can take weeks for some news to be widely distributed among service teams. It is wishful thinking to believe that they would have a bulletin prepared less than a week after Elon shared on Twitter that a
retrofit should be possible. An R&R (Remove and Replace) is not a retrofit.
As with the backup camera recalls (which you also chose to ignore on Twitter), anyone who wished to have this worked on before it was ready for their vehicle was expected to pay ~$295. Or you could be patient and wait a few weeks for your service center to contact you via the mobile app.
While the "next-gen capabilities" have been advertised since the Palladium refresh, there was no clear direction for how Tesla would accomplish this until earlier this year when they decided to switch from native implementations to using Steam's new OS/application in a VM. Until this week, it also didn't matter logistically what hardware was in their vehicles, as nothing yet made use of the upgraded MCU-Z.
It is valid to be frustrated. It is valid to be put off by being told to expect something upon delivery, which wasn't true. But to directly and voluntarily do something you weren't told to do, and then complain when it doesn't go your way, feels misguided.
