The person left after Tesla made $890 million from selling these coupons in just three months. Read from source...

- The article is written in an informal and subjective tone, using phrases like "leaving after realizing $890 million in revenue" and "all-consuming mission", which implies a negative sentiment towards Tesla and Ashlee Ramanathan's departure.

- The article does not explain the concept of regulatory credits in detail, which may confuse some readers who are not familiar with the topic.
