For this topic, the key excerpt is:
"Customers who previously purchased Full Self-Driving will receive an invitation to Tesla’s Early Access Program (EAP). EAP members are invited to experience and provide feedback on new features and functionality before they are rolled out to other customers."
That is the promise to prior FSD buyers. I recommend limiting your class action lawsuit to getting access to the Early Access Program, plus monetary damages for lack of access in the intervening months.
I appreciate you not being a troll and actually having a conversation with us on this!

Stop basing your information on someone's personal twitter account. these are not Teslas official posts.
On the contrary, Elon and Tesla have stated that his Twitter can and is used for official company statements. This is in writing and filed with the SEC.
