Seems unlikely/strange that all these clones would miss this little thing of using the derivative instead of the accelerometer directly so that it 'actually works'

That's the same as being pulled towards the earth at 1 gee. Both are acceleration from the accelerometer's point of view. I'm not sure how to convey this well in text, but maybe try installing a sensor reader (e.g. https://f-droid.org/en/packages/de.rwth_aachen.phyphox/) and looking at how the accelerometer values change when you move it in various ways
