Let's cut right to the chase, shall we?
In This, the second episode of The X-Files eleventh season, Richard Langly, a.k.a. Ringo but more commonly referred to as simply Langly, is dead. His body, we learn, was cremated prior to his burial back in season nine's Jump the Shark. We know this because Walter Skinner tells us so. The Lone Gunmen are dead.
Without getting into a long discussion about this being a wasted opportunity to bring back the popular trio (as was done in the comic series), what we can say is this: The events of this episode do not completely eliminate the possibility that he is alive somewhere. And regardless, it doesn't matter.
Langly being alive or dead in physical form has no bearing on the outcome of this episode. If you believe the narrative, he died saving thousands from a weaponized, airborne variant of the Marburg virus alongside Frohike and Byers. Yet the Langly we meet in This is digital Langly. Well before his eventual death, he cut a deal with a government contractor to transfer his consciousness to a simulated world. That simulation runs within an NSA governed complex. And it is from that simulation that Langly reaches out to Fox Mulder.
The simulation, says Langly, is as if he designed the world. With the Ramones alive and playing every night, and all the hot dogs he can eat. The New England Patriots never win.
And everyone is a digital slave. Mulder, he says, must shut the simulation down.
