The saga started on Sunday, when Musk tweeted an apology for Twitter being slow in “many countries” and implied that the poor performance is because the app does over 1,000 “poorly batched” remote procedure calls to load the home timeline — basically saying the app has to reach out to other servers a bunch of times and wait for a response for each request. Frohnhoefer, who tweeted that he’s spent six years working on Twitter for Android, quote retweeted Musk’s statement saying it was incorrect. Musk has done the same thing several times in response to news stories about his companies, but unlike those instances, Frohnhoefer actually went on to provide an explanation for why he thought his boss’s tweet was incorrect.

The conversation between Musk and Frohnhoefer is messy, spread over many threads and hours (which Twitter ironically makes difficult to see and follow). At one point, Musk asked Frohnhoefer what he had personally done to fix Twitter being slow on Android — though remember that the conversation started with Musk’s apology for it being slow in “many countries” — not on Android. But Musk’s seemingly final word on it came in response to a discussion on whether Frohnhoefer should’ve brought his concerns about the original tweet up in private on Slack rather than publicly calling Musk out. A commenter in the thread said that Musk probably doesn’t want Frohnhoefer on his team after the developer tweeted that Musk should’ve asked questions about the slowness issues privately, to which Musk replied, “He’s fired.”
