The piece is, likely, bullshyt. I haven't read it.
SecDef publicly calling for the "Pentagon" to end "offensive cyberoperations" (whatever that means) against Russia is *yawn*. My read: doesn't affect any ongoing op in IC, which is where any significant "cyberop" (once again, whatever that means) is likely to be conducted.
Since this work is considered extremely technical and it takes place in a notoriously opaque area of government, it's easy to scare a bunch of people into thinking this means something it, in my opinion, does not.
Notice all these stories are short on true analysis (what is an "offensive cyberoperation," when did "the Pentagon" begin its current campaign, why?).
Also, it's likely this is part of an ongoing op. Whose op? I guess we will find out in the future.
