While technically true your first statement is very misleading.

The SF Fed has a nine-member board. Three members are appointed by the Board of Governors of the Federal Reserve System, who in turn are appointed by the president and confirmed by Congress.

The remaining six members are elected by banks.

You can certainly make the case that banks should have less influence over the fed. But this isn't at all unique to SVB.
