Matthew Patsky, CEO of Trillium Investments, a Boston fund that manages more than $3 billion, put forth a shareholder proposal this year asking Facebook to clean up its act by setting up a risk-management committee to sort out what went wrong with the data consulting firm Cambridge Analytica, the manipulation of Facebook during elections, and other privacy screw-ups. A copy of the shareholder proposal and letter to Facebook can be found at Trillium's website: trilliuminvest.com.
