I'm commenting for Hive account@dutch because he's gone to sleep.

We are able to confirm express consent for the less than 1% of users who install Charity Engine through the website, as that is the only installer available for us to analyze.

From Spyware Techie:

According to our team of specialists, CharityEngine often comes bundled with other programs, which is why many users do not notice how it enters systems and cannot remember downloading it themselves.

This sounds like about as much consent as leaving a sneaky checkbox checked by default in a bundled software installation.
