As I explained in the article I seriously doubt that any more than a tiny number of these passwords are still valid. And there is no reason for them to be, having already been widely available, indexed (and cached) by every search engine, archived at archive.org, and downloaded by thousands or tens of thousands of people. Anyone who would use this data maliciously probably already has it.
Much of this data is the same data monitored by sites like haveibeenpwned.com and a dozen others. Facebook scrapes these. Lastpass will send you alerts. The risk here is minimal; the research value is much more than you realize.
