I don't think that's all there is to it. For the first part of last year I started paying for a subscription to several news sites of various scopes. I still got some annoying ads, albeit fewer, but annoying emails and other messages increased because they needed my engagement (because they were STILL selling ads), and my daily reading was still overwhelmingly flooded with click-bait style journalism (again, they need my engagement and that's what they think will engage me).
