I would expect it to drive monopolization, since you now have to have resources and competency in yet another thing. Seems like it would be harder on incumbents.

EDIT: since people are downvoting this, I should clarify that I’m not advocating against the policy, it just doesn’t seem intuitive to me that this policy would reduce monopolization (data privacy may well be worth the tradeoff). If I’m wrong I’d love to be corrected!
