The 2 headlines and claims aren't mutually exclusive. The FBI investigated reports that the Russian government was tied to the hack, and concluded they weren't.

The 2 headlines and claims aren't mutually exclusive. The FBI investigated reports that the Russian government was tied to the hack, and concluded they weren't. That doesn't mean the actors weren't Russian citizens and/or living in Russia. Just as an example, the Target and Home Depot breaches were almost certainly conducted by the same fairly well-known group of Russian hackers and fraudsters, but they have no known ties to the Russian government.
