Im a professional gamedev. There is pretty much no indie on earth who actually depends on cloud systems to work, because that stuff is expensive and indies dont have money. Thats a megacorp thing particularly from AAA publishers. Indies are either singleplayer (this is 0 problem) or they have local servers. That article is paid for by the lobbysts and completely incorrect and wrong.
It's not just clouds systems. SKG might not cover it but what happens if Steam hypothetically shuts down? Many games are built on the Steamworks API for things like matchmaking and networking. Those will stop working if Steam is gone which could bring down many multiplayer titles with it, even if the games have local servers.
Valve themselves could make a solution (a server emulator for instance). Or publishers that use Valve servers for matchmaking can just replace them. The first solution is for games that are no longer supported. The second one is for those that are.
