He also lost me when he attacked React. React makes developing web UIs sane. It's a web UI framework written by grownups who took a CS class. UI is a pure function of state. Why is that so hard? The fact of the matter is this: the web was never designed to be a rich application UI. Web UIs of any kind are a hack on top of the web. By definition they are embracing and extending because they were never there in the original HTTP/HTML spec to begin with. They're so popular because deploying actual apps to endpoint devices is so horribly painful by comparison. This guy also doesn't understand what true embrace/extend tactics look like. Embrace/extend/extinguish is when you embrace something, extend it, and then drag the market into a state where the use of other things becomes impossible. Nothing Facebook is doing is doing that to the web as far as I can see. Web sites that don't use React, Relay, etc. work just fine. If anyone is doing E/E/E against the web it is Google with Chrome and all the complicated nasty standards (e.g. the WebRTC mess) that it's dragging everyone into that only Chrome implements well. But even there I think it's a weak argument. I use Safari and Firefox and the web works fine in those 99.9999% of the time.
