"You should have expected us"

Regarding the cryptic writing found at the scene of power line sabotage in Arkansas:

"You have expected us" is a line previously employed by the hacktivist group Anonymous.

The video below is two years old, and is largely dated.

But it the final seconds, it proclaims:

Operation Blackout. Engaged.  We are Anonymous. We are legion.  We do not forgive. We do not forget.  To the United States government:  You should have expected us. 

Now the question is, is what's happening in Arkansas part of a some kind of Anonymous affiliated operation, the work or copycats with similar goals, or the work saboteur(s) with other motivations who decided to false-flag with some Anonymous imagery to throw authorities off track?
