As long as Bitcoin stays open source and voluntary, I don't see a problem of anybody funding its development even if it's a CIA or JPMorgan. What we should fight for is to have an open market for alternative currencies.
Cryptocurrency is best served as a natural monopoly. Bitcoin will likely be the only popular cryptocurrency. It's not a like it or leave it type of thing. We do no not need it controlled by the government or the largest bank.
Recently a lot of very interesting ideas have come up which, if implemented fully, would either require a new currency or a hardfork of Bitcoin. There is no way to stop the old blockchain from continuing, so we willl end up with at least two currencies if those ideas are implemented. Do you think the ideas should be forbidden and buried?
Currently I see no reason to choose anything else than Bitcoin, but I'm not sure I can resist when something much better comes up. E.g. something where the blockchain isn't needed. Control is an issue here as well, of course.
