We're not blaming him for it happening.
We're blaming him for shrugging his shoulders at a outside attack on a American company that effects millions of people across multiple states and will cost us a lot of time and even effects airlines.
Biden even called a emergency over it.
Emergency declaration issued in 17 states and D.C. over fuel pipeline cyberattack

And ultimately this is about also making us look weak and easy pickings. Because someone put the hurt on our countries resources effecting millions of people and our president said "it's not our problem".
You're hand waving is disgusting.
