One draft report for 2017, misfiled in the hopelessly mismanaged Haiku Inc. "website" after many years since the last one (in 2010) does not count as "yearly financial reports" and since this is a one page summary it can't be said to be "detailing financial transactions" either.
Mostly decisions aren't made at all, anywhere. That financial report you're calling "yearly" took months for the Haiku Inc. board not to agree. That's right, months, not for an agreement, but for the _lack_ of any response whatsoever to be taken as tacit permission to just publish it anyway.
Sarcasm aside, I don't know what decisions you're referring to which "aren't made at all, anywhere" -- the board agreed to a cost increase for server hosting earlier this year so we could switch providers.
You put "website" in scare quotes, and I don't know why -- in fact they deployed a new website last week, which is much better organized than the previous one was.
The point is, Haiku, Inc. is not as responsive as we'd like, indeed. But the money isn't going into a black hole, and they do pull together to get things done when we really need it.
And most decisions are made in public, on the haiku-inc or haiku-sysadmin mailing lists.
