From <https://www.schneier.com/blog/archives/2017/09/iso_rejects_nsa.html>: The ISO has decided not to approve two NSA-designed block encryption algorithms: Speck and Simon. It's because the NSA is not trusted to put security ahead of surveillance ... I don't trust the NSA, either. I should point out that SELinux was created by the NSA, too. The difference being that that has been subjected to years of careful independent scrutiny.
