They brought this to themselves when they set the launch date to June 18th for this monstrosity.
This is a feature that is still in preview.
I fully agree that the feature is poorly conceived and we need a response. But "radio silent" is severe over-exaggeration for a feature that the general population does not have access too.
If we don't get a response by mid next week, even a simple "we are delaying the release and will have more information soon", than I would agree.
But this is not an actively exploited thing running on un-expecting users.
