There’s finally a dent in Big Tech’s armor.

On Friday, a federal judge handed down a mixed ruling in Epic Games’ antitrust lawsuit against Apple. The judge determined that Epic had failed to prove that Apple was a monopoly — score one for Apple.

However, she also found that Apple was violating California laws mandating that companies provide transparent consumer choice. As a result, Apple won’t be able to force game developers to make all game purchases in the app itself — of which Apple takes a 15 percent to 30 percent cut. Score one for Epic, and every other app maker, too.

This certainly deals a blow to Apple’s App Store business. But it’s also a new chapter in the antitrust saga that is just beginning to unfold as law makers, advocates, and companies take on Big Tech. Because it shows that Big Tech just might be vulnerable.

“I don’t think it’s nothing that this is actually the first major ruling where a big tech firm was dealt a blow,” Matt Stoller, the director of research at the antitrust advocacy organization American Economic Liberties Project, said over the phone. “It matters that Apple lost.”

Stoller thinks the ruling could also indicate that judges might be willing to rule against Apple and other companies, which he said, five years ago, “would have been seen as crazy.”

“It suggests that judges are more inclined to rule against Big Tech these days,” Stoller said.
