... and in any case, the changes were made with Wilde's full acquiescence. Wilde was a very successful author in his day and, had he been fussed, might well have had printed "private editions" for his friends.
This earlier unpublished edition is (presumably because at $25 I haven't read it) an interesting and potentially fascinating behind-the-scenes looks at what Wilde was thinking, a more private view of his way of expressing fondness for men.
We certainly should not take away from this (based on what I've read about reading about the new edition) that there is anything "new" in the story. Homosexuality was as common place in educated Victorian England as it is today in our world; the meaning of Wilde's texts for the intended audience were not lost in the published edition.
