Best things you can do is write letters to people and agencies, get some people thinking. Next best thing you can do is start using FOSS yourself. My coding abilities are html in the 90’s and enough Java Script to pass my 100 level comp sci class. I wish I had the money to add to the communism that is the OSS world but I provide data for Crowdsec and I share the Debian and RaspberryPi OS’s torrents every three months, when they are released.
