"ditch Wikipedia" seems a bit melodramatic. Nobody should rely on Wikipedia as the sole source of any information, but it can be a useful starting point and usually has enough references to back it up. People need to be more careful about examining the source of claims in general. Including what is shared with them on social media, YouTube videos, news articles, etc. But that doesn't mean those mediums are no longer…
Definitely, if they call for ditching Wikipedia over a single contributor in the title of the article, how much are they exaggerating about other things?
