What about classifying businesses according to the Debian guidelines (main, contrib and non-free)?
This would undermine the goal of a Free Software Business and the GNU Business Network. This is also why e.g. Debian is not listed as a recommended GNU/Linux system by the FSF and the GNU project simply because Debian includes non-free software.
You will only end up promoting non-free software by allowing business who promote and/or support non-free softawre to be listed as a Free Software Business or as a business that is part of the GNU Business Network.
The FSF has a list of Free Software business already, known as the Service Directory (www.fsf.org/resources/services/).
Here are the requirements that need to be fullfilled for a company/person to be listed in the Service Directory:
| This is a list of people who have asked to be listed as offering | support services for GNU and other free software for a fee or in | some cases at no charge. To have your information added to this | list, please send an e-mail to service@fsf.org. | | The information comes from the people who asked to be listed; we do | not include any information we know to be false, but we cannot check | out any of the information; we are transmitting it to you as it was | given to us and do not promise it is correct. | | Also, this is not an endorsement of the people listed here. | | We have no opinions and usually no information about the abilities | of any specific person. We provide this list to enable you to | contact service providers and decide for yourself whether to hire | one. | | Before FSF will list your name in the Free Software Service | Directory, we ask that you agree informally to the following terms: | | 1. You will not restrict (except by copyleft) the use or | distribution of any software, documentation, or other technical | information you supply anyone in the course of modifying, | extending, or supporting free software. This includes any | information specifically designed to ameliorate the use of free | software. | | 2. You will not take advantage of contact made through the Service | Directory to advertise an unrelated business (e.g., sales of | proprietary information). You may spontaneously mention your | availability for general consulting, but you should not promote a | specific unrelated business unless the client asks. Please | include some indication of your rates, because otherwise users | have nothing to go by. Please put each e-mail address inside | "<>". Please put nothing else inside "<>". Thanks!
Cheers.
