It doesn’t matter if one has bought the software or not. They are as it is today falsely advertising their product by stating the car already today has the hardware installed to be FSD. It has no mention that purchasing the software is a prerequisite for this to be true.
You are *painfully* out of focus here.
Every computer is advertised with it's CAPABILITIES, complete with the understanding that, for more advanced things, you need to buy the software to support it. I don't expect to buy a computer without and Operating System.
Video games are ALWAYS advertised showing games - software - that you have to buy.
When I bought my Model 3 over 6 months ago, it was made QUITE CLEAR that FSD was not yet available and that this was a 'pre-purchase'.
