As the artical mentions, the Chinese version has been blocked since 2016 - shortly after Wikipedia made the decision to move to mandatory HTTPS via HSTS. I'm not sure how recent this is but it seems that the site is also on the HSTS preload list used by most browsers - even within China (it seems Chrome is very popular there). It seems they have just gotten arround to blocking all of the other languages this year.

ESNI seems like it would work pretty well. Although the PRC firewall could likely be used to block ESNI and/or TLS 1.3 and force plain-text SNI.

Well actually they have been blocked all language about a week ago on May 6th or 7th.
