What's the bottleneck in getting a Macbook like touchpad experience in a modern non-Apple laptop? Is it software? Some specific company that won't sell parts to anyone else? Patents?

I have tried several laptops, and nothing has even comes close in the last ten or so years.

I am hoping you might have some unique insight into this!

PS: Framework Laptop 16 looks great, will order one later this year and then get a GPU with more vram whenever available in future.
