I trust the little guy.

The editor of Gizmodo knows very well that "Apple" gets clicks and in this case he's trying to generate free press for his obscure book. His suit doesn't quite meet the standard of "frivolous," so I don't think anybody is getting sanctioned for it, but it's certainly not filed in good faith. It's not even an issue of "trust." What he claims is inherently ridiculous. You can't copyright historical events, and presenting it as a Cold War thriller isn't some radical creative choice of "tone." The dry facts are pretty thrilling on their own, and the extra-thrilling parts (car chase) are inventions of the film.

How many other people are they doing this to?

Not stealing from? Literally billions of other people are being treated the same way by Apple every day.
