The tussle with the apparently former Twitter employee started when Musk posted a tweet about the app’s performance in some localities, stating “Btw, I’d like to apologize for Twitter being super slow in many countries. App is doing >1000 poorly batched RPCs just to render a home timeline!” One of Twitter’s Android developers, Eric Frohnhoefer, disagreed, saying he had spent six years working on the app and Musk’s statement was wrong.
I have spent ~6yrs working on Twitter for Android and can say this is wrong. https://t.co/sh30ZxpD0N

Frohnhoefer went on to clarify the app doesn’t actually make any RPC calls and delays are caused by the time it takes to interact with Twitter’s United States-based servers, rather than RPCs being built into the app itself. After some back and forth, Musk directly confronted the engineer on what he had done to improve the app during his time at the company. Frohnhoefer gave a detailed response citing issues he had helped fix, problems he saw with the app, and possible solutions. Musk’s eventual response was less constructive.
