I can stop to receiving Insider Preview builds but the options are only to stop for 1, 3, 5 or 7 days, not permanently - same behavior on both device.
As wrote in Anniversary article, you can stop recevi9ng insider builds and turning in production when current official build is UPPER than current insider build.
So, before August 2nd, everyone could have the chance to exit Insiders, and left Redstone becoming official, then overpassing installed build. That's all.
The rule is: a system can only be upgraded, NOT downgraded.
