Spouses are the real victims in these situations. Part of the pain of infidelity is the humiliation. Airing a whole community's dirty laundry just makes it worse for the victims.
In the context of those affected by the fallout, if enough are affected, then one could claim the opposite: That it makes it easier knowing that so many were affected that nobody is passing any judgment on their specific incident because everyone is in the same boat - thus the humiliation is actually less.
