I mean we privacy nerds all love webapps but the reality is the people actually in charge of S&P500 companies hate them. They really, REALLY want to fingerprint your device and use it as a verification and tracking mechanism.

Until that changes, webapps aren't going to sell.

Even Google tried multiple things to "sell" the idea of webapps (e.g. Polymer project) in 2011-2015 and failed.

Funny enough, Wechat kinda succeeded at webapps in China because there's a strong user preference to stay inside one monolithic "everything app".
