You're talking about about OOP-B, everyone here is talking about OOP-A. OOP-B isn't really a part of what's being discussed.
Anyone can bring it up, but "education" isn't relevant here. It's not what was discussed in the article, or the comments.
As neither of you, I'm talking about OOP. Nobody's limiting the discussion to composition or inheritance. Otherwise we'd be talking about how 'inheritance sucks' rather than 'OOP sucks'.
