This is interesting. The fact that it's a tough pill for everyone in universe to swallow and the fact that it is, technically speaking, impossible to an extent creates suspension of disbelief issues for the heroes. If characters in game are rampaging because of the virus, then none of the players will be rampaging in real life to any noticable extent until they're forced out of the gear. This creates a sort of time limit for decisions on the part of the individuals before they start acting and before evidence will appear in social media on a large scale. It'll be seen as a bluff until there's more evidence.

As for the whole, "Chosen ones," thing, it very much appears to be more of a plot motivation for those individuals and as encouragement for them individually to participate. Calling upon their potential honor and such.
