This is flatly false.

Schiller emailed Sweeney asking for assurances and Sweeney responded with:

> Epic and its subsidiaries are acting in good faith and will comply with all terms of current and future agreements with Apple, and we'll be glad to provide Apple with any specific further assurances on the topic that you'd like.

Without reply, Apple summarily terminated their developer account a week later. It seems obvious, in retrospect, that Schiller's email's goal was to establish a fig leaf of Apple having reached out before doing this.

It is indeed true that Sweeney has tweeted many criticisms of Apple's DMA plans but there haven't been any threatening noncompliance.
