You're probably one of the most knowledgable on what went on behind the scenes. However, I would at least doubt that Apollo still had any contact with EZScape or pretty much anyone from the speedrunning community since July or generally most of 2020. The video was made well after that in October.
If you take a look on Twitter when Apollo posted his video two days ago, almost nobody from the community had any way to contact him or knew people who were close to him or even had contact information -
including Goose who hasn't had contact with him
since July or so. EZScape also seemingly
had no contact information available to share with others, though of course that should be taken with a grain of salt.
