From what I've read, he apparently declined to pay his bill to Google Cloud Platform (he also was not paying rent at his... headquarters? one of them, I dunno? in Colorado), so then they cut him off - which he apparently did not expect - so he unilaterally instituted an emergency rate-limit for all posts yesterday, which in turn caused embedded Twitter feeds to constantly keep trying to connect and get the content that it always has been able to before, and since it could not connect it just kept trying, over & over, over & over, over & over, over & over, over & over again.
He DDOS'd HIMSELF!:-P
What a stable genius he is showing himself off to be... /s
Though still smarter than Huffman, who followed him blindly despite the circumstances being totally different - like on the off-chance that Musk actually had a thought & a plan somewhere buried in there, what is Huffman's excuse for following him? It reminds me of a particular Star Wars quote by Ben Kenobi actually... :-D
