I don't mean to be rude, but I had taken some valuable time to apply, just to be sent a canned email saying that "internship selections are over". In that light, can you justify advertising that you are still accepting interns?
If you didn't get an interview, you should have received the message, "[We] do not have an open slot in our current slate" – sorry that we weren't able to offer you an interview, but best of luck with your search for an internship.
