Google was and still is the canonical Web Company. Android went with Java and custom APIs over the web stack. More than a decade later and this hasn't changed. The new Android UI layer is Jetpack Compose - again, not the web.

At the same time, Palm decided to redo their own OS and they went all-in on the web stack. They even called it WebOS. Palm were a well known name with momentum and talented staff, but WebOS was a failure partly due to poor performance.
