Your accusation even conflicts with the basic definition of malware:
> Malware is any software intentionally designed to cause damage to a computer, server, client, or computer network.
I know what you're getting at, but why chose such a loaded term that doesn't fit?
> A wide variety of types of malware exist, including computer viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, and scareware.
It specifically mentions spyware, so let's take a look at that definition:
"Spyware is a type of malware that aims to gather information about a person or organization, without their knowledge, and send such information to hack another entity without the consumer's consent."
The very source you pasted this definition from (Wikipedia) goes on to list spyware as a type of malware, and the page for spyware lists Onavo as an example.
