Great points here
1. The banner happens last month of the year (Wikipedia being the perfect analog). Yes, there are mixed feelings and it's not the world's best experience :P
2. Our entire data set is available to download as in bulk https://openlibrary.org/developers/dumps because we'd love to see a decentralized p2p version
3. https://github.com/mouse-reeve/bookwyrm Mouse who used to work @ Internet Archive has a decentralized version of Open Library (Bookwyrm) and it's worth checking out.
4. For the last 5 or so years the Internet Archive has been cultivating a dweb/dapp community and integrating with IIIF, Dat, IPFS, gun, bittorent, webtorrents, and others and hosting regular summits and meetups https://blog.archive.org/2018/07/21/decentralized-web-faq/
5. The wayback machine is an interesting case study: it turns out, incentive structures (even things like FIL/filecoin) haven't been able to perfectly crack the nut on getting folks interested enough to preserve the whole wayback machine. There's petabytes of material and there's a powerlaw about what people care about today. Internet Archive realized what we care about today may not be the same as tomorrow, and so there's a cost eaten (the incentive comes from economies of scale generated by intrinsic desire rather than $). And in a way, this centralized solution (economies of scale) IS the solution a community came up with. It has flaws and advantages (tradeoffs), such as centralized points of failure, and I think the archive would be (and has been) ecstatic to explore improving these opportunities.
