RT wiki says he's still there, but came across this.
"In July of 2018, Matt received some controversy and criticism due to his political views.
Several users on Twitter posted images of Matt Peake’s personal YouTube channel that listed several political videos he had liked that were public, the videos included were ones from PragerU, which is considered the most controversial political channels as well as controversial figures such as Paul Joseph Watson, Stefan Molyneux and Tim Pool. Fans of Funhaus accused Matt Peake of being “alt right” in defending alt right ideologies.
Matt Peake in response posted a political compass image that showed him being a centred leftist as well as a sad face drawn on as a joke to debunk the rumours of him being alt right but to the dismay of some people still believe he is still alt right. Since then Matt Peake has not touched on this situation."
Probably made him want to stay off camera.
