Just because the studio shut down doesn’t necessarily mean they lost their jobs. Often (especially for a giant publisher like Embracer), talent gets moved to other studios since it’s easier and cheaper than hiring new people.
But when you’re part of a smaller studio, you have creative control and freedom you don’t get when you’re a cog in someone else’s machine. People who go into this industry typically are looking for that more than just a salary, especially since other non-game jobs usually pay better. Although, idk what Volition was like internally, so maybe it sucked to work there.
