No, they shouldn't.

Any method that does not operate on an instance of an object should be static.

There is no point in requiring an object instance if you don't need it.

There are very specific cases that prescribe their use such as passing a class method to a C API that needs a function pointer or a means to create certain patterns such as Singleton. Generally you don't want to use one unless there is a good reason.

They are otherwise discouraged because their use beyond some limited cases implies you have global data present since they don't have automatic access to the 'this' pointer. That violates OO principles such as data hiding.

It depends - a static method is necessary in a OOP language such as Java or C# if you really just need to write a stand-alone function. In this case you might create some sort of Utility class that contains various static methods.

In my opinion, static methods are simpler than instance methods, and therefore they should be used as much as possible.

The thing is to know when it's not possible: which is usually, i.e. whenever the method needs to read or write object/instance data members.
