> without the incessant nagging and limitations that X subjects non-logged-in users to
That is directly the result of the evil pull of advertising. "Logged in" users are more valuable than "non-logged in" users to advertisers (because logged in ones are identified) and so what you are seeing as "nagging" is Shitter (formerly X, formerly Twitter) desperately trying to increase its ad revenue at your expense. You are watching enshittification right before your eyes.
Actually you can write "Xitter" ("x" is pronounced "sh" in the standard transliteration of Chinese and many other languages, although most of them are not really widespread, like Basque https://en.wikipedia.org/wiki/Basque_alphabet and Maltese https://en.wikipedia.org/wiki/Maltese_alphabet).
