About Turing stuff... I actually heard about it first time when they announced the Sailfish move. Digging a little, AFAIK Turing phone is descendant of failed Quasar IV project, which had ambitious goals about unique OS:

QuaOS, Quasar IV’s operating system, is a fusion of Android, Linux and the Quatrix encryption software. The Quasar IV provides unprecedented security for Android users.

If the security/encryption related things were already built on top of Linux with some Android stuff on top of it, integrating/porting them to Sailfish shouldn't be much of an issue. This, of course, assuming that such software actually was written.
