The short answer is that a great many techy's are working on decentralization because the present centralized model has a lot of serious problems, like Facebook et al making their money selling ads that may have malware, and also selling your data to who-knows-who.

There are many projects to decentralize the web. IPFS gets so much attention because it is such a broad platform that other technologies (like Ethereum) can operate on top of, and because in some important ways it is farther along than anybody else.
