The real question is what do you get out of advertising to people who don't have any money? Kinda squeezing blood from a stone.
You'd be better off saying you use those people to A/B test changes and filling idle GPU batches while giving paying customers a more consistent experience.
There's lots of people who are willing to spend a lot of money on 'real things' while not spending anything on bytes. It's the tech companies which have created this expectation of free services. Many non-tech people I know are relatively wealthy and think likes this.

Psychographic data. What they learn from these folks will create the most powerful manipulation technology yet.
A bunch of people pay to remove ads, and a bunch of people that are happy to give businesses their attention (view ads) I'm exchange for services... I.e. Gmail, YouTube, but don't feel they use enough / are annoyed enough to warrant $15-25/month.
Some brands are okay with impressions.. you can build trust in your product be advertising it for weeks/months and when the user does make a purchase that brand is on the mind.
