A family of Microsoft relational database management systems designed for ease of use.
Yes change is hard, but inevitable. The way I read the tea leaves this was a feature that was too costly to maintain and not used enough, and a perfectly good alternative exists in Excel.
Not used enough? How does MSFT know? That's where that "Customer Experience" thing comes in. If you turn that off, MSFT does not know you use Pivot Table all the time and that's one more strike against the feature.
