It appears that Musk is currently aligned with more extreme right wing conservative voices, he appears to tweet and retweet in their support, he blocks the oposition of such governments in Turkey and India, he more recently seems to support both Trump and Bolsonaro, both right wing election deniers who encouraged attempts to overthrow elections.

I have no particular insight into Musk, I speak only to the observation that he appears to support some voices over others and as such that is "his voice" - those who say things he supports and whose opponents he blocks.
