I received the email today, then went to check my triplebyte profile. On visibility settings, I saw the default public visibility is still ON. Probably they are cancelling this feature anyway, but still showing showing ON in public visibility seems like another messed up!
PR to pull the visibility toggle from prod is under review. Much of the eng team is out for the long weekend, and we may not merge until tomorrow. However, the public profiles themselves are not in production and we are canceling the feature.
