Patron organizations affiliate themselves with the FSF through financial support.
For individual-donor acknowledgements, see ThankGNUs.
Through corporate patronage, companies and other organizations can support the FSF in its mission to defend and protect computer users' rights. In return, they can enjoy the patron benefits. Being an FSF patron demonstrates to a large community of dedicated free software enthusiasts and decision makers that you value their work.
