There are a coupe of things I find incorrect in your statement.
The improved 1080P webcam was released almost ten months ago.
There have been complaints with the Studio Display webcam; also the 13" MBP webcam because it's the old webcam. But not really the new laptop webcam.
Apple will release Continuity Camera in a couple of months, not now, with MacOS Ventura.
Apple has been demoing new features in beta ever since WWDC so to me the timing is coincidental and only bad optics if you are cynical.
Apple doesn't set the price because Belkin makes it. Apple made the bumper.
I had and returned the iPhone 4, but I don't see this as the same thing.
That's like saying that Apple should admit that the M1 SoC was a mistake because the M2 SoC is an improvement.
Continuity camera is great for people who have Mac minis, Mac Studios, MacBooks in clamshell, hooked up to external displays, etc.
