The page you quote has only existed since April 2019. Tesla sold cars with AP2 since October 2016. During that time, the description of AP was held at Tesla.com/autopilot (and still is!), which says:
For someone that bought between October 2016 and April 2019, what were they supposed to read to understand what the "promised" features of the car were? My 2016 car listed auto wipers, cruise control, highway auto steer, auto braking, etc as features of the car in the manual, on the website, and they were functional during a test drive. It was delivered with none of those, and some of them still didn't exist a year later, despite the website giving a specific date (December 2016) as the date they would roll out.
The idea that it's clear with Tesla what is a promise vs what is marketing puffery is far from true for an average consumer. Why is tesla.com/support/autopilot more binding than tesla.com/autopilot? Even if you only use the /support/autopilot, in April 2019, it said this:
And now, in 2021 after many revisions, it says:
Hmm, seems like they are at least 16 months late on something "promised."
