Lid sensor calibration requirement: what on earth is Apple 'thinking'? WHY DO THIS?

I do not understand why a lid sensor that requires software 'calibration' would be installed in a laptop. The purpose of a lid sensor is to determine if it is open or closed. A hall sensor works just fine - always has.

Now Apple decides to add an 'angle sensor' that requires software calibration if it is ever replaced, even repaired. This is nonsense. Considering the price of an Apple product, this (persistent) use of redundancy does not indicate Apple is concerned with or respects consumer interests (to save money and own a product that will not require additional maintenance)

There has to be limits on American corporations destroying positive innovation with delinquent ingenuity.

Anyone with a sensible answer to why this 'angle sensor' makes sense in (from 2021) 2023? Cheers.
