Ah, good point. Here's confirmation of that from the NYT:
https://www.nytimes.com/2017/03/03/technology/uber-said-to-c...For the people who have options, some could still be entirely wiped out by this, but it's not as big a problem for new hires.
It's still a problem, though. As the Reddit discussion makes clear, people are benchmarking against things like Google. The equivalent equity package from Google 2 years ago would have gained 30% in value, while the Uber one has lost 30%. Assuming $200k in equity from each place, that's $260k for Google and $140k for Uber, or nearly a 2x difference.
That would sure make me think about jumping ship.
