My post retraces a historical progression of social media, and it was indeed called "Twitter" at the time. You can scroll a bit down and you'll see "X" a bit below. In general, actually reading the articles you comment on won't hurt you.

I did read the thread — and I’m specifically referring to the third (and final) diagram where it still literally labels X as “Twitter.” No amount of timeline layout gymnastics explains that. It feels less like faithful documentation and more like a pretext to take a swipe at the acquisition by “some guy,” which then segues into the whole “getting cooked by the algorithm” bit.

That's clinging to straws. Many of us still prefer to call it Twitter since the new name makes no sense, especially when placed in a sentence.

That was an example of a social media company changing, with users not being able to migrate their data. Scroll a bit further and you'll see X.
