There’s an absolute torrent of things to read about Apple vs Epic Games, or Epic Games vs Apple (which is more proper, IMO, since Epic Games is the plaintiff here).
Here are three relatively short reads that bring up the major points at the heart of this case:
From Protocol: 4 big takeaways from Epic v. Apple, day one
From Seeking Alpha [free reg-wall]: Apple vs. Epic: Key takeaways from the first day of the antitrust trial
From Michael Tsai’s blog: A terrifically curated rollup of tweets and quotes from the tech community
There’s too much to try to snapshot any of this here. But if you are interested in the blow-by-blow of this case, start with these three, and you’ll quickly get a sense of the major players, as well as the key issues in the case.
