Elon responds asking how much of the company do they own, and what their views are on freedom of speech. Presumably hinting at the fact that the KSA assassinated Jamal Khashoggi for his journalistic endeavors into how they were utilizing Twitter troll farm operations to influence public opinion about their government, and generally being a well known dissenting voice.
