What to Blame for the Atmosphere Change in Re-enactment Camps? Personal View

Lately, I have been seeing quite a few posts by friends announcing that they are quitting the Viking Re-enactment hobby. This is sad and worrisome. Apparently, the reasons for leaving are due to a lack of authenticity, show fight, and atmosphere. I think they are overlooking the main contributing factor: the hobby is not changing, the people are, and consequently, so have those saying farewell to the hobby.
