Are you sure you're talking about Teslascope / myself? I've not tagged Elon in a post in weeks, and never not about the Model S / X changes. The last time this happened was when we'd see Cyberpunk in the Cybertruck, which he had hinted at on many occasions historically.

So, respectively, I am unsure where you're getting "beating this horse to death tagging everyone and Elon and such" from.
I often get confused for NotATeslaApp or other accounts...
They didn't announce the existence of HW4
until nine months after it appeared in the first vehicles.
They didn't acknowledge the Pedestrian Warning System
until two months after it appeared.
They didn't acknowledge the major brake changes to Performance trims that cheapened the brake pads
until a year later.
They didn't acknowledge when some Model S and X were delivered with 8GB Infotainment Computers, which prevents access to Steam, and subsequently demanded $2500 for a paid retrofit, despite the order page displaying and mentioning it.
And dozens of other notable changes.
So, no, that is incorrect. Tesla does not always announce changes. They only announce changes with major revisions, such as the transition from Raven to Palladium for the Model S and X, or when they are legally required to such as when the Ryzen computer reduced range.
