The vast majority of apps are malware. In both Apple's and Google's app stores. It's gotten to the point that apps are assumed to harvest all information they have access to, store it permanently and sell it to anyone who asks.

If you define malware so broad that every app meets your definition then the term kinda loses its punch.

It's the software ecosystem that has changed, not the definition. Spyware was always included. You can check the history of wikipedia article on malware if you don't believe me.
