Because homosexuals are wrongly discriminated against, and this guy would be the first to step up and open the door. People shouldn't have to live in fear of ridicule; the guy feels like he can't open up this pretty major part of his life that he keeps secret every day. That's just a horrible existence, and one he shouldn't have to go through. Heterosexuals don't experience this; for them to 'come out' implies that there was a need for them to hide, which there never has been. Courage amd righteousness will get media attention, but the attention is not the reason he's doing it (imo). This is more about stepping up for the community of homosexuals who haven't yet had the guts to do it, and, ya know, standing up for himself and his beliefs.
