Few things:
(1) That article buries what they're actually talking about, which is the Bay of Pigs invasion, in the bottom third of the article and barely does it any justice;
(2) Anyone with any understanding of the Cold War or access to Google knows what Bay of Pigs was, there's no Hollywood cover-up;
(3) Fulgencio Batista seized power (again) in 1952 with a military coup d'etat. He's not someone I would go out of my way to defend, considering his mafia connections and repression, like that article did. That's like saying roving police death squads are great as long as your gated community is safe; and
(4) Yes, the US left the Cuban anti-communists out to dry. Just like we did with the Rhodesians, South Africans, and others. Yet we wasted huge amounts of resources fighting a war in Vietnam. We could've took the money we wasted in Vietnam, supported Rhodesia and South Africa with it (I don't know "saveable" Cuba would've been), and saved thousands of lives, but no.
This picture sums up our involvement in Vietnam the best for me. Those are all brand new USGI boots we
gave for free to ARVN. Once we left Vietnam late in the war and the North Vietnamese were closing in, the ARVN troops collapsed like a house of cards. The troops took all the great equipment we spent millions, if not billions, on, and abandoned it to run for their lives.
