In summary it was about publishing it with zero price, requesting donations, selling hardware with it, etc. It rejected because authorities decided SambaPOS does not have major market share. That means it may happen again in the future. So I'm trying to form a foundation behind SambaPOS to develop our future projects as a legal non-profit entity. This is not an easy task like writing code. The hardest part is convincing people to think SambaPOS as a useful tool for their business.
We stopped accepting donations months ago because it causes legal problems to us. For now the best way to support SambaPOS is helping us to reach more people. That might be a positive comment, photo submission for our FB page, an answer to a question or maybe just an idea to share. Every bit helps.
