Earlier quoted context omitted.
Issues like that are part of why the law is only going to apply to new releases. If you still choose to license something you can't release later, and it's critical to the game's operation, then that's a deliberate liability and you'll need to replace it.
That sounds like a bad incentive. Lots of games license software like Photon to run game servers. For many games, building something like that is a non-starter.
And it's not expensive for Photon to do that, so I don't see why they wouldn't add that feature for a modest price or even free. (And that's assuming the license doesn't already allow it.)
