Apple’s trackpads are even better now. How has nobody figured out Apple’s 2010s trackpad technology?
I think because the focus is so much on the trackpad technology itself, which may be a misplaced focus. My fear is that the solution may involve rearchitecting the entire application-GUI stack to get it working on Linux. Why? Because Apple's trackpad is not a mouse emulator, it's a first class input device all the way up to the application. Trying to make the driver really smart is fruitless if you throw out all of that rich information and try to reduce the inputs down to what a mouse is capable of.
Luckily Linux is closer to figuring it out than Windows and I'm watching several issues on libinput and wayland which are trying to address it.

There are also various 3-finger swipe gestures, and force touch lets you click on things with different levels of force to do different things.
The only Linux application I've seen that uses smooth scrolling with acceleration is Firefox, and that isn't nearly as smooth as macOS scrolling (which is available in every application).
It seems that this is in fact the chief complaint of the folks who commented above you. It seems like they're saying that they choose to purchase alternative goods because of that behavior. That seems critical to me, no?
Edit: I knew this would get downvotes, but it's true in my experience. The closest exception is Microsoft themselves, and even then their hardware focus is limited and mostly intended as a demonstration for their OS customers.
