As you said, there's literally no formal process for retail investors to communicate to the funds. This startup organizes retail shareholders to use their rights via petition, e.g. https://www.yourstake.org/ask/vanguard-demand-companies-disclose-political-activity/ https://www.yourstake.org/ask/vanguard-demand-companies-disc... . So as a verified shareholder, you can signal your support for various issues, and the startup then arranges a meeting with the fund managers if enough people support the idea.
