I have seen similar bugs in the systems I oversee because network libraries love to retry requests without sane limitations by default. But I never saw them make our rate limiters sweat. It's slightly more annoying when they hit an API which actually does some expensive work before returning an error but that's why we have rate limits on all public endpoints.
I also guess that the webapp is the least of Twitters traffic and the native apps probably don't have this problem.
I agree that this is probably not the bug at the root of it all. But I also don't believe the story that Musk is selling for why he's in effect shutting down the site. But both could be true and I'm still thinking about other potential reasons, a complete waste of my time, but it's a weird mental honeypot.
The book "Nothing is true and everything is possible" describes Putin's use of misinformation to maintain control of the populace and eliminate democratic types of politics, but it really feels like it applies here too. There will always be Musk fanbois who will parrot whatever he wants them to say, but most know it's just self-serving BS. And anybody trying to get to the root of everything gets easily sidetracked into narratives that feel right but have zero data backing them, like this bug.
Anyway, highly recommend this book if you want to see a likely path for the future of the US:

My favorite is when things are claimed to be impossible, that Elon's lying because the thing is impossible, but then it happens anyway.
Where Elon gets in trouble is he's wildly over-optimistic on a few things, such as AI. He predicted an AGI would take over in 5 years around 2015 or so (so we're 3 years off), and I think he really believed it. That's why he's always claiming things like self-driving, and doing it without sensors or whatever. His paranoia of AGI and his over-confidence on self-driving have exactly the same root cause (believing AI will conquer all). Elon has had so many instances of overcoming status quo expert predictions (whether on solar energy, battery-electric vehicles, reusable launch vehicles, or whathaveyou), that I think it makes him increasingly unable to very effectively listen to experts.
And he's also incredibly gullible and easily taken in by all sorts of scammers, including rightists and just plain sycophants telling him what they think he wants to hear. Which is increasingly what he's left with as everyone else who is sick of his bull has left.
