There are two criteria that software must meet to fit this definition:
1. The software must act against the interests of the computer user.
2. This must be done "secretly".
I unfortunately do not know much about the Reddit App for iOS so I can't make a judgement as to whether it fits definition 2. I think I can say with confidence it fits definition 1.
I believe (s)he wanted imply reddit's official app displays a lot of inline advertisements and other stuff that makes it difficult to determine what is legit subscribed content and what is sneakily inserted by reddit.
The ads are. The data being collected to target those ads is not.
I guess a non-malicious way of collecting the data for ad purposes could be to collect it locally and offer the user to review it before sending it off.
