Using ten domains as an example is not evidence. Did anyone check the millions of sites on the internet?
How do you know there were not lots of sites Elon "likes" that were being throttled?
Did anyone test more than 100 domains?
This could have easily been a bug.
e.g. a bug that was happening temporarily because an in memory cache was breaking for certain indexes.
Oh well, people like casting stones — personally I am going to wait for more of the facts.
(Note: I haven't said whether I like Elon or not)
(Edit: If my post is so disagreeable, I would love if someone could take the time to give me a short reply as to why)
