We are a big community and a lot of users are not payed directly by the main sponsor. As Open Source is, a lot of users working together, independent of place and profession. If this network would not exist, open source would not be so popular as it is today.
In special there would miss a lot of Linux distributions, if Debian would not exist. Debian is since the beginning of Linux a leader, and never really has been a company (just as an example). It is a Community as we are. Even if we are not a 100% non profit community.
