Popping open the link you provide only works for me in incognito mode on desktop. In regular mode on desktop, it appears to work, but very shortly after beginning to scroll, it pops up a box saying I have to log in to see more. On mobile, I can't read anything at all; there's a box saying I have to log in.

It's not really public-square distribution in any general sense. Hence the popularity of proxies like nitter.
