Lavishly using OOP, FP, etc is a bad idea if the tools are a mismatch for the solution's implementation. OOP is widely used for business applications (notwithstanding legacy COBOL systems) because object-oriented design generally is a good abstraction for business concepts. Perhaps Java is over-applied due to IBM for a long time thinking that they could replace COBOL with Java. Then along comes object-oriented COBOL.
