I would agree with the premise that there's reduced number of editors. I would agree wikipedia should try to figure out why.
It's not immediately obvious to me, from OP, who are leaving but I have a pretty strong understanding who.
It's also quite impossible to survey the people who left. When you survey those who remain, you're getting the complete incorrect cohort.
>automated toxicity detection
They never really define what is a toxic comment. Their sources seem to suggest the gender gap, task related disagreements, harassment survey from 2015, and something about arabic wikipedia.
All the while there are clear rules against things like personal attacks. So you have to kind of find rather subjective examples and you somehow automated it? That seems frought with inaccuracy. Yet they seem to find some correlation? Oh wait they don't provide those numbers. I bet it's pretty bad for them to hide them. Perhaps it's my mistake and I failed to find them.
>voluntary opt-in survey of the 3,845 Wikipedians conducted in 2015
All data prior to the actual problem occuring will be a red herring at best. Again, wrong cohort. This is like surveying non-cancer patients and making conclusions about cancer patients.
>The automatic detection of offensive language in online communities has been an active area of research since at least 2010
Offensiveness is subjective and clearly 2010 is too early of data.
What I see from this study, is cherry picked data from at least ~7 years ago. Why are they even doing this? Are they trying their best to find an explanation while being intentionally blind to the problem?
I'll just throw down. How about the better explanation? Wikipedia became biased and can't really be trusted anymore? Why contribute to something because has become a political tool?
I could point at John Stossel's work on showing wikipedia's bias. I could offer wikipedia cofounder Larry Sanger's blog on wikipedia's bias. There has even been countless live examples where influencers modify wikipedia for greater truth. Provable on live video that the facts were incorrect. They then edit wikipedia and then it's near instantly reversed.
How about wikipedia's own curated 'reliable sources' which reads like a they only accept sources with only 1 type source; a particular establishment left wing viewpoint.

Whether or not fox news is reliable, it's not, it was practically the only source from a differing viewpoint. They purged all the rest.
Why is the reduced numbers of editors? People left wikipedia because it's not reliable and trustworthy anymore. People aren't leaving because someone on the internet hurt their feelings.
Wikipedia is absolutely free to continue in this path, but they will be in decline for doing so.
