Async comm in web apps often keeps them responsive when the native app experience is: spinner... spinner... spinner... spinner... lock up the window and you can't move it... spinner... spinner... spinner... "should i reboot the whole machine first thing or should i try killing the app with task manager and starting again?"

Their killer feature, being able to share a link with anyone at the company and instantly collaborate (live!), is made far easier on the web platform vs native. “The input lag” frankly does not matter in the big picture, imo.
