So they form a corporation and donate to several Super PACs that are technically (though not functionally) independent from the campaigns they wish to support, and that will do with the money what the campaign would have done (buy millions of dollars' worth of ads on TV and social media).
Technically you are right, they can't donate directly to campaigns by forming a corporation here, but they can get close enough that if you squint you can't tell the difference.
>" This would be legal in the United States as well. They would just first form a corporation and then donate it from there."
These statements were factually incorrect. You are making different claims.
