Any platform is threatened by any app that becomes bigger and more important than the platform itself. They invested in ie for the same obvious reasons that Apple tightens control over apps on the AppStore. When you spend more time in an app like Netscape then windows is less relevant and you’d be more likely to use some other platform that could still run Netscape.

ChromeOS takes it a step further where the platform is the app you used most on from the PC.
