They get promoted for fucking with them. We were in the middle of a big fight with Microsoft support over a product defect. They literally updated the product docs in realtime and revised the sizing guidance for the product to be about 5% under our sizing. It was too specific a number to be a coincidence.
We were at war with them, so the team was capturing the documentation and timestamping it. They gaslit us to run the clock so the product would slide outside of mainstream support.
