Do we have neutral sources for these claims and emails?
Apple said Sweeney threatened to breach contract and didn’t repudiate in private. Epic claims it didn’t threaten and did repudiate. We’re in a he said she said absent independent sourcing.
The source for the tweets (from your original comment: "Sweeney allegedly tweeted that he would breach his contract with Apple") are Sweeney's Twitter feed which you can read as well as I did. Did you find any threatening non-compliance?
Even with screenshots, and assuming no false claims (which IIRC are entirely legal so long as you don't swear under oath), there's plenty of ways to mislead by omission while saying only true things.
