Was reading a related thread on Twitter as well.

The PCs given an exception will no longer receive any new future Insider Preview builds from the Dev Channel but will still get Cumulative Updates for Windows 11 leading up to GA. As I said, there is a distinction between *new builds* here.
How are they supposed to receive "Cumulative Updates for Windows 11 leading up to GA" when they are being forced out of the WIP and instructed to install Windows 10?
