I agree. Trying to shove everything into the browser is absolutely stupid. Native apps are better than doing things in the browser in almost all cases. But that's not trendy, so people don't chase after it.
Native operating systems are garbage at maintaining user privacy and become maintenance burdens when too many applications have been installed and even uninstalled on the machine.
While not perfect, a browser tab is a stronger sandbox than you can easily get in any other context.
