* Organic Maps devs are from Belarus, company is registered in Estonia. This is very difficult setup already, and I can imagine authors just want simplest setup possible. Perhaps they do not want to waste energy on nonprofit that is very very difficult and expensive to do internationally!
* If they sell the company so what? Create another fork and move on. It is opensource, but that does not mean authors can not get some money!
* Biggest expense for Organic Maps is hosting and mirroring map data. Is this fork going to use (and pay) their own servers?
* Is there list of developers and contributors behind this fork? I only found "us" and "we" and "community"!
