Basic data analysis should have caught that a non goverment body was important enough to exempt, but they just didn’t do it.

What kind of “basic data analysis” are you referring to? I mean, it would be nice if that was a practical idea, to assess nearly every Twitter account and determine if it should have an exemption, but I don’t see that it is. You either have an insanely labour-intensive process, or you have an imperfect automated process. Or, you just draw a line in the sand, as they did.

I don’t think you can claim that Twitter has a “responsibility” in any meaningful sense, either. It’s a private website, they get to set the rules and change them as they see fit. That’s how it’s always been. The responsibility lies with the organisations tasked with distributing the information (which also doesn’t include NERV, they do it voluntarily).

I don’t even think Musk made this change to try and make money - in my opinion, ever since he was locked into the purchase the plan changed to running it into the ground. On the way down, Musk can experiment with all sorts of horrible things - such as API charges - and while they won’t get away with everything, the things they do get away with will set the standard for any social media platforms that come after the business ceases operations (primarily due to the debt accrued in the leveraged buyout Musk performed).

So yeah, Musk doesn’t give any shits, the whole operation is intentionally destructive. But like I say, he didn’t drop the ball here with Japan, he did it ages ago.
