I don't think tesla "funding" will have any material effect on his political activity.

Tesla could completely go away, and he would still be the world's richest man.

This is just a sad case of tilting at windmills...

Protesting General Dynamics, or any of the other companies making bombs or landmines that are still dismembering children around the (third) world would be much more appropriate. I wonder why no one is protesting Space X instead?

Protesting an electric car company is just counter productive, regardless of who owns it...
