Either way, there's not much revenue coming in to most games by the time the developer wants to abandon them, and Photon's not getting paid much either. There's a lot of ways to make this work out monetarily.
I’d love to see you rise to the challenge. If you think there’s an opportunity to make money here, “lots of ways to make this work,” perhaps take it up yourself.
Can you name something that's stuck on the cloud on a technical level and also couldn't be substituted with a mild dev effort?
Right now I don't think it's a good money making opportunity. Becoming one would need Photon or some other significant service provider completely refusing to license their software in a way that's compatible with this law, and assurance that they'll continue to refuse while I build my entire product around supplementing/replacing them.
