I cannot think of a less trustworthy source of information than Emil Michael on the All-In podcast. Why on Earth would you take his statements at face value? I grant that nobody in this situation is totally trustworthy, but if it's his word against Dario's I'm believing Dario 10 times out of 10, and it's astonishing and dismaying that anyone might do otherwise.
Keep in mind that Emil Michael's job at Uber was to slander and destroy their political enemies. What makes you think he hasn't continued exactly as before?
