I am probably going to get torched for saying this, but it's just my opinion and random thoughts. I think there are two different situations going on with Jahi's family:
1) As many have shared, I think Jahi's mother is being driven by feelings of denial and guilt (who can blame her, it is her child) to keep Jahi on death support and is praying for a resurrection (miracle) but medically that just is not going to happen. She cannot see through her feelings of denial and guilt to let Jahi go. This is where someone professional needs to step in and help her cope through these very dark days. She has been quoted recently expessing concerns that her daughter is not being fed, is starving, glad she is a "thick girl", and tells her daughter that she is losing weight, but still "looks good". Jahi's mother needs help.
2) I think the Uncle is fueling this media circus, along with the help of the opportunistic lawyer, and is being driven by $$$$$$$. Yes, I do think the Uncle is devastated to have lost his Niece, but at this point - he appears (based on FB posts, Twitter posts, IG posts, etc....) to have moved past the devastation. The longer Jahi is kept on death support, the longer the charade goes on. Which is just sad to not let Jahi rest in peace, and to be using her like this.
Separate from the Family, I also feel that this New Beginnings is using Jahi's story to gain financial backing and awareness of their facility. Based on the comment upthread about any negative posts on their site will be deleted and people would be banned for posting negative comments. That just screams being opportunistic to me.
Just my opinion, and a sad tragedy no matter how you look at it.
