The technology to realize a peer-to-peer alternative to GH is here. We just need to make it happen. IMO radicle.xyz is the most promising one right now.
The only path that makes me hopeful involves a combination of 1. FOSS software (ie forkabke when the warlord misbehaves) 2. user owned / governed networks, so the warlord can't easily get extractive against their users.
The fact that they assume that decentralized web equals immutable and global by default shows ignorance. You should take a look at SSB and Radicle, if you want a different dweb than IPFS.
