Tenuous connections, indeed.
From her previous article on this film: Spielberg halted production "because he didn’t want to anger and incite terrorists." Meaning incite them to attack the Olympics that were ongoing at the time.
Cowardly? Yeah, maybe. "Halted production to avoid upsetting terrorists"? That makes him sound like a co-conspirator. It's a pretty vicious smear.
This article is easily as bad as the worst liberal tripe out there. There are plenty of things that Debbie could criticize Spielberg for, if she has an axe to grind (and clearly she does) - but this is a big, big stretch.
