Apparently corporate structure gave him power over the board. Historically this kind of structure was considered undesirable and illegal in a public company, but beginning in the 2000s there was this idea that "visionary founders" should be able to demand absolute control, ex: Zuckerberg

By personally owning 84% of the voting shares. This coup was doomed to fail from the start.

The same way Mark Zuckerburg does - he maintains majority control.
