It is deliberate.  IMHO it isn't a bug.

This is because `inhibit-splash-screen' is a variable alias for
`inhibit-startup-message' and startup.el does the following:

~line 872 of startup.el: 

    ;; Run the site-start library if it exists.  The point of this file is
    ;; that it is run before .emacs.  There is no point in doing this after
    ;; .emacs; that is useless.
    (if site-run-file 
        (load site-run-file t t))

    ;; Sites should not disable this.  Only individuals should disable
    ;; the startup message.
    (setq inhibit-startup-message nil)

    ;; Load that user's init file, or the default one, or none.

First, it loads your site-start.el file which frobs
`inhibit-splash-screen' (which is the same thing as
`inhibit-startup-message'),

then it disregards that frob, resetting the value of
`inhibit-startup-message' (which is the same thing as
`inhibit-splash-screen'),

then it loads your init file, e.g.: ~/.emacs.  If you frob
`inhibit-startup-message' or `inhibit-splash-screen' (which are
different names for the same thing) in your .emacs or in your
`custom-file' or by loading another library from your init file the
value will not be reset, hence:
