20 years ago there were a lot of peer to peer applications. For example, Skype used to bounce calls across peers. Now, all calls gets routed through big-brother Microsoft.
NAT and American assymmetric bandwidth ISPs both killed this business model and now we are stuck with tech monopolies like Cloudflare. I see this ipv4-only strategy as another monopoly tactic to kill competition.
And in Asia, it is getting more difficult not to get stuffed behind a double NAT (CGNAT), which means you can't even play games without using big-brother rent-seeker services (no port-forwarding/upnp). But at least here you get ipv6 for free and everything just works.
