Nah, it's even simpler than that: after shoving enough surveys in users' faces (as they seem to semi-regularly do across all Meta products; I've had at least 2 in WhatsApp alone over the past few months), they've collected enough misclicks and drunk responses to be able to interpret them as lots of people wanting ads.
I was playing a lot of Beat Saber in April and got a survey which asked bizzare questions like “Do I want to use VR to manage my calendar?” They went so far as to ask for times I might be available for a focus group then they ghosted me.
