I don't understand the thesis that Musk is somehow pro-Russia. Generally his ventures are against Russia interests:
SpaceX, launched in the aftermath of Russia being uninterested in selling a leftover rocket to Musk, now dominates the launch industry to the detriment of Russia, among other things halting the cash flow from NASA to Russia to carry astronauts to ISS.
Tesla and former-SolarCity, reducing use of oil, while Russia is a major oil producer.
Starlink provides communications capability to the country Russia is attacking.
However, a likely macroeconomic slump in (electric and other) vehicle demand and Musk’s erratic way of running Twitter are real problems. I think these get the blame for stock issues, rather than the bizarre Russian thing.
