You've been given the joke answers but the real answer is that the Suns biggest stakeholders bought Reddit.
Ok but for real, r/nba teamed up with Reddit Community Funds and they're doing a fundraiser for the Boys & Girls Club of America. There's also prizes and shit. And I believe that the two fanbases that donate the most for that week get the sub adorned in their colors for a time. Cavs and Warriors did for the first week.
Pretty cool initiative imo, rare r/NBA mod W.
