WordPress is a free resource developed by developers all over the world, this (good deed) can be translated further down to the other people who are not tech savvy, and this resource can be used to create solutions that will help other people.
This is for example by creating websites where people can air their civil grievances and also websites for activists for human rights and activist activities and then offering these sites for free to those who can use this to help improve other peoples lives. This is just one among many ways WordPress can be used as a charitable tool more so as to spread information and to air content that could help make a difference.
