The original argument was to "flatten the curve" to prevent hospitals from becoming overwhelmed. By that logic, areas where the hospitals have not been overwhelmed (which is most of the United States) should be gradually reducing restrictions, and only maintaining the restrictions necessary to prevent hospitals from becoming overwhelmed.
Lately, the prevailing argument seems to be that we need to shelter in place because virus cases will increase if we don't. That was not the original justification. Of course cases will increase! The question ought to be, will they increase to the extent that they overwhelm hospital capacity?
Most of the people quoted in the article agreed with shelter-in-place orders in the first place, and now they are being labeled as "skeptics" for sticking with the original rationale.
