Ask HN: What Can We Do?

It seems to me that there are people in this forum who are either decision makers at tech companies, or are in a position to sway those decision makers. One thing that occurs to me is that as schools switch to distance learning models, companies like Zoom could (if even only temporarily) offer their services for free to affected school districts. Given that most of us are not first responders or health care professionals, what are the other opportunities for us to make a valuable difference at this time?
