It just means "Do not blame me for things being the way they are."
I assume you heard or read this in A Christmas Carol by Charles Dickens. Scrooge complains when the Ghost of Christmas Past is showing him a particularly painful scene from the past. The Ghost responds by saying "I told you these were shadows of the things that have been. That they are what they are, do not blame me!" Although the Ghost is showing him the things that happened in the past, the Ghost is just presenting the truth and isn't responsible for what Scrooge has done in the past. It's akin to idiom "don't shoot the messenger!"
This phrase suggests that things or people are as they are and should be accepted as such, without placing blame on others for the way they are. It emphasizes personal acceptance and accountability.
