I wasn't around much when that happened, so won't comment on it.
I can say that when the original P85D 0-60 time (with one foot rollout, as we now know) was improved from 3.2 seconds to 3.1 seconds, via software update, people here were very pleased, and many of us said so.
i think one major point that your most recent post fails to address is that there is a huge difference between a company delivering more than their customers have paid for and a company delivering less than what their customers paid for, or taking away functionality that the customers have already enjoyed. The former is nice, and generally appreciated at least somewhat. The latter infuriates people, and depending on the severity, could be considered fraudulent.
