Very briefly, I think Ben Scott and I agree on most of this range of policy responses here, but on this one there might be a bit of distance between us. In the long run I'm not sure we can make that distinction between political and non-political ads in a viable and sustainable way.
Ultimately, whether it's for commercial or political activity, both are seeking to influence our behaviour. Why wouldn't we, as either consumers in a consumer protection realm or voters in an election integrity realm, be allowed to know how our behaviour is being microtargeted using incredibly sophisticated systems to target and nudge our behaviour? I see different baselines for both, but the easier solution is to make it all transparent.
