I don't read the article (besides the clickbait headline and the author's "take") as Tesla "giving up". No marketing is changing, no plans for taxi services are changing. This is about the company's famously captured board giving their beloved CEO flexibility on how to meet their ambitious-sounding targets, by using vague language in the definitions. This way if Tesla fails to hit 10 million $100/month FSD subscriptions, they could conceivably come up with a cheaper more limited subscription and get Elon his pay.
