Despite the media attention, I don’t think this is any threat to the integrity of the encyclopedias’ content.
The Wikipedias get waves of activists and are used to dealing with them. The ones who don’t take the time to understand Neutral Point Of View, their stuff gets removed. The ones who do, their stuff stays and their cause gets accurately described and represented. Best case, we get more good new Wikipedians.
This applies to any activist for any cause whatsoever and has applied at least since I started on en:wp in 2004.
The advice I have for activists is: strict neutrality with excellent citations will do your cause justice. Everything else will be removed.
The broader advice is: there is no plausible attack on the integrity of the encyclopedias themselves that is not already something we are quite used to dealing with on a daily basis for many years.
I wonder if the presently prominent group of activists have taken in this one in the quest to have their stuff stick.
