As someone else stated it is the measurement of the totally battery capacity, NOT the number of cycles. While I don’t want to defend anyone here this is not planned obsolesce, it is a mitigation strategy to prolong the general use of a device as it degrades. However yes, Apple probably should have given a notification to users of degrading / worn batteries of their state and that performance may be affected.
