I just clicked... indeed, the article is so misinformed that even some simple half-trues (whatever that might be) mentioned in the article are completely out of place... But this kind of articles show me a different problem: the relation between seniority and expertise. I'm growing tired of an industry where more years of 'experience' is conflated with more expertise. Maybe one of the culprits is not OO itself (which I personally do not regard as a bad paradigm), but the myriad of really bad and lousy texts and examples teaching and explaining OO concepts: I think there is out there a complete generation of developers that just don't design good software.
