I recommend reading the whole article but have quoted a key part.

The president argued before the Supreme Court that ObamaCare’s regulatory scheme cannot work with out the individual mandate. Yet he has now exempted millions of the very people he most needs to comply with it. This exemption siphons good risks out of the Exchanges and destabilizes the risk pools for both the standard ObamaCare plans and the catastrophic plans. Participating carriers set the rates for their Exchange plans with the expectation that these folks would be purchasing bronze, silver, gold, and platinum plans through the Exchanges. But the healthiest members of this now-exempt group are the most likely to go uninsured or purchase a catastrophic plan. So Obama’s blanket exemption makes those risk pools older and sicker.
This blanket exemption also destabilizes the risk pools for the catastrophic plans. It opens those pools to lots of people over age 30, who have higher health expenses than people under age 30, and whom the insurers were not expecting to buy catastrophic plans when they set those rates.
....
This exemption also shows Obama is not interested in bipartisanship. Just as Republicans would have worked with him to delay the employer mandate, they would have happily worked with him to craft an exemption to the individual mandate. In both cases, the president took drastic, and possibly illegal, action to avoid working with Republicans. (It may yet dawn on Obama that he is the reason we don’t have a “normal political environment.”)
