The latest rant about the Android app and '1200 RPC call' strikes so close to home. I'm in software engineering, about 5 years ago I was a senior director at a US company (with a UK presence) and we got a new VP of engineering. He clearly wanted to find problems to get excuses to can people. Someone who wanted to brown nose would make some crap up, or equally don't know what they're talking about so spout some b.s., and the new VP would latch onto it exactly the same way Musk has here. He clearly has no clue what he's talking about and is suffering a strong case of Dunning-Kruger.
In the case here Musk claimed the Android app made 1200 serial RPC requests to render the timeline. There's so much clearly wrong with this. Firstly its not RPC, Twitter uses GraphQL over HTTP and it was pointed out by the Android developers immediately that there is a single GraphQL query that then performed around 1000 internal queries against microservices to aggregate the result, but this all happens concurrently. Musk wasn't having any of it, so his next response was:
And guess what, 2FA stopped working because they killed the microservice(s) that ran it. He's a complete fraud.
