How's this for research: In 2011, when Facebook tried HTML5 for their app, an iPhone 4 ran the Sunspider JavaScript benchmark in a little over ten seconds according to Anandtech. Today we stopped using Sunspider because phones and browsers are so much faster there's no point to it, but an iPhone runs Sunspider in ~70ms. 150 times faster! And today we have APIs for camera, storage, video, 3D, notifications, threads, WASM, etc that didn't exist back then either. When developers can save 30% by going with the web, that's a real big incentive to explore the new performance and new APIs the web has today...
