For anyone who has seen website or software development up close, breaking some things while fixing other things is largely how it works.
This stuff happens on every other social platform all the time too (really ask yourself how many times you've experienced a weird glitch that prevented a post or made it so you can't like something, or which logged you out of Gmail, etc.). The main difference is, the inner workings are basically never made public.
Google Docs goes down, and you have no idea why. You just know you can't access your presentation for an hour.
In this case, you're seeing it happen in real time and you have some little insights into the BTS of why errors are occurring. As such, you have someone to blame when ordinarily you'd just curse some nameless, faceless tech dweeb or you might assume there's been some malicious hacker doing bad things.
Twitter is a very - most likely unnecessarily - complex piece of software..
Breaking it in one way or another is probably fairly easy... But breaking it is also the only way much of it is going to get better and unlike a the next edition of Madden, they're working on it while users are in the system.
Musk's theory seems to be to break a whole bunch of stuff very quickly, figure out what's needed, and fix the unintended consequences. It's definitely one way to go and it's only something he could do by taking the company private. And while it's probably a race against the clock, my bet is that Twitter will be a lot better for it in the end.
We shall see.
