What? This a mandate in law that requires a company to do work in order to comply. Studios will spin out LLCs for a game so that if it fails it doesn't end up as a liability. Unintended consequence: more dead games.
Really the parent company should be held accountable for that. But that is a more general problem with LLCs that is already causing significant harm.
It's impossible for the law to cause more games to die, because already the default fate of online games is for them to die. If, with the law, a studio chooses to use an LLC to create the game to conditionally release sources once it shuts down, that was a game that without the law would have died anyway because the studio wouldn't have chosen of its own volition to release sources.
