The entire article is just sloppy "Zuck bad, AI bad" clickbait. There is absolutely no indication anywhere that they refused to help.
As much as my gut instinct is "screw Zuck" the reality is "we don't really know the full picture, and the Wilderness Legacy knew what was up well enough to handle the problem so they did"
Personally I'm a bit bummed out about it because there's less that I want to read and the articles make the comment section... well, like the articles. I shouldn't complain though - someone took note of where the traffic was and it wasn't people like me. Also I still visit the site, it just seems like there's for me.
