I found my info at https://www.uamr.de/wem-gehoert-tesla/
Elon Musk ist mit 20,6% der größte Einzelaktionär von Tesla
Elon Musk is Tesla’s largest single shareholder with 20.6%
I did not assume that his stake was this high, but I did not care enough to look for a second source. So, thank you for providing more reliable figures!
I have no idea what your are asking or implying.
I guess it’s a joke that he is involved because he did help the project, even if not on purpose?
