A few weeks ago, I did a write-up about a concerning development at HealthCare.Gov: The growing push under the Trump Administration to not only partner with 3rd-party web brokers (which has been done since the first days of the ACA under the Obama Administration), but to actively promote those third-party brokers over HealthCare.Gov itself.
In and of itself, this wouldn't be too problematic as long as people are still ultimately enrolling in fully ACA-compliant policies and receiving ACA subsidies if they're eligible for them. Hell, one of these 3rd-party authorized web brokers even has a banner ad at the top of my website...which I only allow because this particular one only sells on-exchange ACA-compliant policies.
