This I have to admit is a lame part of trying to draw in viewers for DC comics. Marvel already has Northstar getting married in the main continuity. But the Green Lantern is only from Earth 2, an alternate dimension. (It's not even the most famous one, Hal Jordan. It's only the first Green Lantern, Alan Scott) Honestly, I was hoping they'd make a different character in the main continuity gay and someone more main character. So I don't find this change really controversial when it's a character from a second earth.
