I don't care if they're gay or not but I don't find it necessary to tell the entire world that.

I'm not a youtuber or lesbian for that matter, but I feel like, especially in the youtube community, a lot of people begin to idolize them and look up to them. But then they also get a lot of backlash and backhanded comments about who they are etc.
But within that, I feel it's kind of comforting to have a lot of support from random people, who like you for what you put out there artistically and what not. So maybe in an effort to feel closer to their supporters and have that weight lifted off their shoulder, they post a coming out video.
They probably feel like they are telling people who have supported them (in which case they are if they are subscribed as, if I'm not mistaken, subscribers and views=pay) and will continue to support them so there is no reason to keep it hidden from these people. And it might be less nerve racking doing it virtually, then in front of someone where the can lash out to your face and immediately.
I don't know tho, I'm just guessing.1
