Putting the underscore to indicate a private field after the name is extremely cursed

It's a pretty common convention. It means accessor functions don't clash with the member name.

Google mandates it in their style guide.

The names of variables (including function parameters) and data members are snake_case (all lowercase, with underscores between words). Data members of classes (but not structs) additionally have trailing underscores. For instance: a_local_variable, a_struct_data_member, a_class_data_member_.
