In the 1990's I saw OO as just another tool which was infinitely better than what I had at the time. I hazard a guess that most devs at the time were still working with procedural languages like C, Cobol, Fortran, Pascal or Basic. OO gave you abstraction and encapsulation, making it a little easier to write better code, that's all.

For me it was never OO v.s. FP, it was just OO v.s. the status quo. If OO was hyped up so some guys could make money from it (as the article suggests), then who was behind it? -- Bjarne Stroustrup, Anders Hejlsberg or James Gosling? I think not.
