Not sure if you've seen this, but Electrek is crediting Tesla for creating xLights:

"But the feature is actually also available to non-Tesla vehicle owners as Tesla released it as a new open-source software called xLights. Anyone can use the feature to create a light show and upload it to their car."
Could you maybe clarify on the Github page that xLights was not created by you?
