They wrote that piece well and linked to archive.ph so people can see the history. They have a snapshop from July 10th with 'bisexual' erased, but as of July 11th, it is back. As I write, the text they cite reads:

Before the 1960s, almost everything about living authentically as a lesbian, a bisexual person or a gay man was illegal.

It still omits transgendered as it has since the Februrary 'purge'.
