Your comments regarding change in 20 years is rather over the top. I used to work at eBay and there has been massive change to the platform both internally and on the UI front. There were major changes rolled live to site in terms of search, mobile and web/desktop. Behind the scenes, there was movement from in-house to open source technology in a major way. Movement from 30k windows servers, to linux cloud (w/250K VMs on openshift), to docker to kubernetes. Moves on the client facing code from new implementations in java(raptor), then to node.js and more. eBay has embraced open source and also open sources many of their solutions as well.
