Many activists carry out their work as employees of or with the assistance of non-profit organizations. Many of their goals need money in order to be achieved, and nonprofits are registered with the government in order to be allowed to receive large amounts of money legally. These activist nonprofits usually get money from even bigger nonprofits, which are connected to big businesses and rich people who control industries. But because many activists criticize things in society that businesses and rich people support, they might not get the money if they are too critical. So in order to stay funded, they may have to change the ideas they have for improving society to be more acceptable to industry.
