Mapy.cz was profitable before, they have practical monopoly on Czech market due shop data (opening hours, menus, user reviews). Recent monetization is just squeeze.
Btw hiking data are a bit obsolete for other countries. They have fork from OSM that is a few years behind.
Donations are going to Organic Maps company. They have 10+ years of history. Most likely to pay for map server traffic.
Non-profit does not guarantee transparency, look at Mozilla as an example.
This fork is just a bunch of anonymous dudes on internet, who setup PayPal and replaced donate button. Until they do map data hosting, there is not much credibility!
Edit: there are 3th party mirrors for manual download, so I guess they can use those.
I would add a few points:
* 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"!
