That’s a larger problem since Safari has a larger userbase. Mozilla is generally at 5% Safari has been at 7-8%. Collectively, Microsoft is fine with losing potentially 12%
On desktops, it is ~9,5% for Firefox and ~5% for Safari (4,5% for Edge). On mobile, I would rather use native app than web one. On desktop, the "native" app is Electron anyway.
At least the native app for Linux comes with a few shared libraries in addition to Electron. So it's not JavaScript all the way down like the website has to be.
That’s actually incorrect. I used Browserstack for testing our web apps. Why buy a Mac when you could basically rent one for your browser testing. We script it out and test out pre-prod web apps.
