Okay, I just read this article 3 times and I do not see where Cathy statements indicate he has “changed course” anywhere, as the author has suggested.
You can find the entire press-release here. No, he's not changing course, but he is saying that the company was incorrectly identified in media reports as "anti-gay". He says that he and his family are pro-biblical marriage, but he "love and respect anyone who disagrees", yada, yada, yada.
So no, he's not "changing his position", he's saying his company's position was slightly misrepresented in the media.
As an aside, I HATE it when press stories only characterize a person's press statement, rather than providing a link to the statement in its entirety. It drives me crazy.
