Well, in Summer 2018 wasn't the base add-on, that you needed for any AP, called something like "self driving hardware"? In addition there was a more expensive software self-driving add-on. Later the boundary changed. The hardware, it emerged, was on all Model 3s. But that was AP 2.x NVIDIA based, while the AP3 Tesla based CPU under development became part of an FSD add-on, along with what came with EAP, and meanwhile the EAP option vanished. A lot of shifting sands.
So IMHO it's more convoluted than either blaming people for not digging into the fine print, OR just looking at the last 4 months and saying "they lied".
Elon Musk says that a Tesla car is an appreciating asset, given FSD. So, let us benefit from that "appreciation". Tesla shouldn't be out to strip that appreciation off for themselves before we even get "there".
