Why do these bigcos use native apps for internal tools? I would think a progressive web app would be easier to maintain for multiple platforms and a good-enough user experience for an internal tool.
Attack surface is comparitively low from outside.
You get full control to what is accessed how. Phishing is basically impossible, you don’t have to trust the browser going the right place doig the right things.
It can be wiped device per device.
It has primary and bi-directional access to storage and camera.
You can give different people different versions of the app without having to maintain whole different sites.
And that’s just what comes to mind in 2 min.
I'm pretty sure both Google and Facebook have way more webdevs available ;)
