So a 48-hour "crunch" week is still less than the standard US game dev work week.
It'd be good to have some better incentives for management to resource and schedule properly (time and a half @ 40hrs, double time @ 48, quadruple time @ 60 would seem an obvious economic stick), but if employees are getting paid fairly I think this is ok. Hope the game is great, and that everyone who is putting in the extra work feels tonnes of pride of authorship in this game. I'm looking forward to it.
And I don't know if its the same in Poland, but here in neighbouring Lithuania - employer can't really "force" you to do overtime, one has to agree to it.
I get that overtime sucks, but it's not unpaid US-like overtime in this case.
They promised they wouldn't do this, then they did it. That's bad.
On a related note, most white collar professionals work 50 hour weeks. Every week.
