In a native client, global mutable state makes many problems straightforward to solve. The web takes that away, puts the state in a funny format in a database or a very limited session store. Even native apps that relied on remote databases still had to orchestrate a bunch of state around the UI, and that was vastly easier without the world resetting every time someone clicked a button, which is traditionally what happens on the web.
