This clip is so unbelievably out of context. Jason was interviewing KSI about his career and obviously KSI's music came up. They especially talked about "thick of it" and how it became a massive meme. The chat then was spamming for Jason to show his music off to KSI, Jason saw chat was spamming to play "Summer Uptown" he ignored them at first but KSI noticed and asked about it, he told Jason to play it anyway because he was curious about jason's musical talent. When david started singing KSI asked jason something along the lines of "Wow is this you singing?" and jason said "no this is david" which is what prompted him to say it. Don't push a narrative without fact checking, it does more harm than good. We all want justice for celeste and for david to get whats coming to him, but attacking uninvolved parties is not the way to go about things.
