There is nothing wrong with having MyLib.getInstance() in a library, but it should return an interface instead of concrete object, so users don't have to write a wrapper if they want to mock it easily or have different implementation provided by your DI framework in tests.
Also the documentation should show that it's not good to use MyLib.getInstance() everywhere in the code.
