As others are saying, it's a culture not the language. C++ and even some Python etc written in the late 90s, 00s era has the same pattern-itis. It comes from slavish adherence to the Gang Of Four patterns books and an obsession with OO generally. Also the languages themselves were weak on non-OO abstractions and ways of doing code re-use, so for example it took forever for Java to get lambda expressions ... so people used one-off helper classes with "invoke" methods, etc.
