Each server is semi-independent financially. Each server registers a business or non profit organization in its own country. It registers a bank account and some form of payment processor (eg, PayPal, Skrill, Patreon, Authorize.net) or sets up its own cryptocurrency wallet. It collects its own donations and revenues.
Each team controls its own income and expenses and pays its own salaries. The money is not handled by the network directly. Instead. it goes to each team's account. When the network needs money, the teams later vote to voluntarily collect it as a team to fund common expenses like software development and networking infrastructure.
We do ask that each server provide an accounting of all bank transactions, so that we have transparency about how much each team earns and spends. Providing an account transaction ledger is enough.
