Not sure where you live, but any big city is likely to have (as a whole) more than enough hotel capacity that a single big event won't cause that much demand. You just won't be able to find a room nearby. Add a 20 minute (or 60, depending) Lyft to the suburbs and they're barely aware that the event is happening.
Also, to get that price you need to look at extended stay hotels. These blur the lines between a hotel and a short-term rental apartment. They do not offer a stay for a single night. They are often sold by the week, or at least with a 1-week minimum
It's weird that this post called it by the short name. The full name, as you typically see in articles, is "X (formerly Twitter)".
It's kinda like "The Artist Formerly Known As Prince". A few places tried to call him "The Artist", but no one ever knew what that meant.
