Linux Kernel 4.17 saw the inclusion of NSA's 'controversial' encryption algorithm Speck. Linux Kernel 4.18 will see Speck being available as a supported algorithm with fscrypt and not everyone is happy about it.
Before you panic or form wrong conclusions, you should know that Speck is not a backdoor. It's just a not-so-strong encryption algorithm from American agency NSA and it's available as a module in Linux Kernel.
The algorithm in question, Speck, is a 'weak' encryption (lightweight block cipher) designed for devices with low computing powers i.e., IoT devices.
NSA wanted Speck and its companion algorithm Simon to become a global standard for next generation of internet-of-things gizmos and sensors.
NSA tried to aggressively push this algorithm to an extent that some cryptographer alleged bullying and harassment at the hands of NSA.
The problem with the algorithm is that the International Organization of Standards (ISO) rejected Speck and Simon.
Google engineer Eric Biggers requested the inclusion of Speck in Kernel 4.17 because Google is going to provide Speck as an option for dm-crypt and fscrypt on Android.
The focus is on providing encryption on Android Go, an Android version tailored to run on entry-level smartphones. As of today, these devices are not encrypted because AES is not fast enough for the low-end devices.

Your cheap jab at "conspiracy theorists" is misplaced. Snowden docs proved that "conspiracy theories" about the NSA were not just true, but that reality was worse than some of the wildest speculations.
Are you asserting that underhanded code hidden in something as large and complex as SELinux would be ovious to any serious code auditor?
