From the article:

While recruiting members with the attractive prospect of being part of an international movement for human liberation, the party’s grueling antidemocratic internal culture produced burnouts, resentful defectors and expellees, and petty authoritarians. And despite the party leadership’s supposed mastery of Marxist analysis, it repeatedly engaged in a series of tragicomic strategic miscalculations, which limited its appeal at every turn.
