I don't know about 'authoritative', but ads do seem to hurt. The existing experimental and quasi-experimental literature shows very bad effects on user behavior:

1. "Measuring Consumer Sensitivity to Audio Advertising: A Field Experiment on Pandora Internet Radio", Huang et al 2018: https://davidreiley.com/papers/PandoraListenerDemandCurve.pd... [experimental]

2."The Effect of Ad Blocking on [Firefox] User Engagement with the Web", Miroglio et al 2018: https://research.mozilla.org/files/2018/04/The-Effect-of-Ad-... [quasi]

3. and my own A/B test: https://www.gwern.net/Ads [experimental]
