Because of low barrier to entry people who didn't learn about jitter, network latencies, BSD sockets, etc.

That is the promise of WebRTC -- just a few lines of JS and you've got yourself Google- Hangouts.

One can argue this happens in web frameworks and other technologies that make it easy to get started with, which is a good thing.

But unfortunately a lot of these easy abstractions can't completely abstract away things like speed of light latencies, limitation of network bandwidth, funky NAT setups and so on.

So far there are very few peer peer technologies that work reliably and are successful.
