EA did this in order to rip off a mod team to make Battlefield 2.

Some modders made Desert Combat, a Gulf War mod for BF1942. They were in the process of making a sequel when they were contacted and offered an office and team in California to finish their mod, sign on the dotted line, turn over all their work on DC2, and promised a bonus if sales went well. Bonus was contingent on them staying with the company up through release.

Well, right as the game was nearing completion, they were offered an ultimatum: you, group of college students: stop what you're doing, pack your bags, and fly to Sweden. You will work in the DICE offices now. If you do not, you will be terminated. Obviously, they all said no. They didn't get their bonuses.

They did become Trauma Studios.
