I'm with you on that. Ideally it shouldn't have been given at all. I just don't see any issue with Tesla updating things to match what the customer paid for. And again, the Tesla website is super easy to use and they detail everything. You know EXACTLY what you are ordering when you order it. I may be bummed if I got some free extras if I was one of these customers but I'd be totally fine if the extras went away since I hadn't paid for them.
I'm wondering if when the customers were handed the keys though if Tesla let them know about this "free trial" of sorts.
