Has FAF an official Treasurer?
The donation page is very basic - Yes, it has a nice (meaningless) graph:
https://www.faforever.com/donation
Also, on Patreon you can decide where the money will go https://www.patreon.com/faf ,but ultimately, those are just words on a screen. You have no tools to verify it, everything is based on blind trust.
Over the years, there must an amount of money accumulated. I doubt the persons who have access to the funding account will make some infamous "exit" strategy like some crypto wallets, but money is money.
There are much better systems to use for stuff like this, where we would have full transparency:
I would highly recommend using this or a similar system, when you want to be open about the funds and giving players a tool to check for themselves what is going on with their donation.
Only if we have access to the whole information, then it makes sense to talk about different budgets and how to get the best value out of it that benefits the FAF project.
On top of my list, would be monthly cups, with a small amount of price money. Those events would give fuel to casters, and people always like to see competitive games (100+ viewers on last tournament, with great games and funny casters).
