Maybe dividing opinions and advocacy into two parts like so: Does the opinion or advocacy have a direct bearing on the success or improvement of the company?

You have a personal stake in Tesla’s success so make suggestions and share your ideas. Your good ideas mean nothing if you keep them to yourself.” Obviously he wants opinions if they bear on the success of the company
