Its a mixed bag. They promised no crunch, but there was crunch anyways. IIRC they gave bonuses and other forms of compensation for the extra work. From what I hear they have a very generous payscale relative to regional norms (Poland) and many team members stand to make a small fortune off the release of Cyberpunk 2077.

Of course executives and investors will make much more off the release then the individuals who made the game.
