In 2019, Destiny was a larger twitch streamer than Hasan. At the time, Destiny and Hasan made collaborative streams with MTV celebrity Andy Milonakis. https://genius.com/Andy-milonakis-the-andy-milonakis-show-theme-song-lyrics
Destiny considers himself to be a liberal commentator and was also a liberal at the time. I think Hasan collaborated with Destiny in the same way as Hasan collaborate with Ethan Klein in later years. Hasan identified himself as a leftist and tried to convert the liberal audience.
Hasan and Destiny split ways in 2019 because they had a debate where Destiny argued that he should be allowed to say the n-word in private without being considered racist. Destiny accused Hasan of saying the n-word in private, in reference to another streamer named TriHex, who is a black man. Hasan called Destiny a "weaselly little liar" and slammed his desk. That's where this emote comes from. 
Hasan's audience grew bigger than Destiny in 2020. Destiny and his community have been jealous every since. In more recent years, Destiny has done paid propaganda for Israel.
The last twitter user, I don't know their name but they have a youtube channel that says Norway is socialist. Also has a lot of tweets in support of Destiny.
