You're being very harsh on Max. No one outside of Tesla knows what is in an update prior to its installation in a car, and then, only to the extent the release notes say anything. Many times the release notes simply say "bug fixes", whatever that may be. Tesla is known to download different versions of the firmware at the same time, and we (Tesla owner) don't even know what version we have received until you install it. To further complicate the matter, sometimes you will receive a firmware update OTA, and once you install it you discover it is the same version that was previously installed on the car (that happened to me twice).
