Bro WTF happened to the acapella group "Maytree"?

years ago I watched so many videos from the maytree group on youtube, but I stopped watching their videos, I remembered them now and when I went to check, their channel doesn't have a profile picture anymore, all the videos were deleted/privated, their instagram has no posts anymore, and I'm not seeing anyone talk about it, when did this all happen? and why the F*ck did this happen?? Did they get hacked or something? Or did they just decided to stop everything? :( This is so sad bro... I really loved their content
