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?
Most of the complaints I've heard about non-Apple trackpads focus more on pointing behavior -- finger tracking, pointer acceleration, palm rejection, etc. -- than scrolling.
That’s because those are old complaints. It’s a moving target though. People are still complaining about problems that were solved over a decade ago in macOS. Now there are a bunch of new features (described in my other comments) that need to be added if you want an experience as smooth and intuitive as macOS on a recent MacBook.
