There was a bit in the thread quoted from an EA document that I found interesting:
Unfortunately, the link to the document didn't work for me, so I can't check it in more depth. This sounds like implicit support for using the Setec CCS adapter on EA equipment, though, which contrasts with EVgo, which has issued a CYA statement that discourages/forbids (I don't recall the precise wording) use of the Setec CCS adapter at EVgo stations. Of course, it's entirely possible that EA could reverse course on this and officially say that the Setec CCS adapter is unwelcome at its stations in the future.
If Tesla is going to allow non Tesla’s access to the Tesla SC network, hopefully that means Tesla will produce a CCS adapter?
