Article is misleading, The librarian of congress is permitted to make exemptions from the DMCA every few years. After exempting cell phone unlocking twice, he declined to do so again on the grounds that these exemptions were not supposed to be used to create permanent public policy.

Congress and the President have now exempted unlocking with a new law, which is exactly what the librarian of congress said should be done if they want to create permanent public policy for that exemption. So they did not overtune a decision of his, he was in support of this, he just insisted it be done properly.
