They agreed to pursue profits back in 2006 when they raised a Series A and then affirmed this when they raised Series B, C, D, E, and F rounds. It's unfair to pin this on going public.

If employees didn't want to be part of capitalism, they probably should have picked a non-profit or a private company that didn't raise >$100M in VC funding.
