Much better to have 100 one megaton bombs.

Yeah, and Russian physicists understand that fact quite well.

The article is complete nonsense.

Even some of us American physicists understand that fact.

Not to mention you don't need 100 megatons to generate impressive EMP. Or that, with a single 100 megaton warhead, if its transport is sunk or disabled, the threat is over: but with 100 individual 100 megaton warheads, each and every one that gets through, is (to a 1st approximation) an entire city really badly hosed.
