Sentebale, a charity co-founded by Harry and Prince Seeiso, has received support from only a few royals, with William and Kate Middleton being the most prominent donors.
Sentebale works towards helping children and young people affected by HIV, and the Royal Foundation of the Prince and Princess of Wales is among its donors.
Additionally, William and Kate are the only royals following the official Twitter account of the charity.
However, things seem to have turned sour between the brothers. In a Netflix documentary, Harry and Meghan appeared to suggest that William and Kate had a hand in their decision to leave the UK and settle in the US.
In his tell-all book 'Spare', Harry again targeted his elder brother, which further worsened their already strained relationship.
As a result, many royal fans criticized Harry for attacking his brother and shared the list of donors, wondering if he had knowingly targeted his brother despite the fact that The Royal Foundation may have approved the donation made to Sentebale.
