Sorry about this "FUD", the truth cannot hurt too much, correct?
The Bitcoin Foundation is paying Devs to work on the core code, so they have a type of control over projected changes.
When the economy gets even more unstable and the establishment gets desperate, here is what could happen:
1) The core Bitcoin code (combined with the blockchain) tracks "every Satishi" from their creation to the current address.
2) It would be possible (no matter how unlikely) to change the code to 'collect' (for the greater good) 25% of all existing Bitcoins and send them to a single address controlled by the United Nations/IMF, for example.
3) The Bitcoin Foundation would need a leader/director who is (possibly) being threatened with serious charges for "heinous crimes" which have no statue of limitations, so the threat is always active... ...oh wait...didn't they just elect Brock Pierce as their new leader?
Whoever controls the code, has power over your Bitcoins. Correct?
Of course the mining pools will reject those code changes? Have the mining pools ever rejected code coming from the main dev team?
Is #2 possible (no matter how unlikely) Yes or No?
Remember that all these coins are types of social contracts. This is very important to understand.
Bitcoin is several things, the client(s), the history (blockchain), the security (miners and nodes via the client(s)) and also a social contract.
Bitcoin's social contract is quite simple, the bitcoin supply is growing according to the mint rate specified when Satoshi first created Bitcoin, all bitcoins can be sent with no need for approval apart from controlling the private key, there cannot be double spends and no way to modify the mint rate.
Notice that the entire value of the bitcoin network is derived from these basic rules, and people have given Bitcoin value based on their belief that those rules are forever and unchanging.
Now if the Bitcoin foundation released a tainted client that stole bitcoins, the social contract would be undone and two things happen: either the community reacts and fights to keep the original social contract in place (by releasing an untainted client and hardforking the network back to where it was) or the community agrees with the change (or can't be bothered to fight via releasing another client) and the value of a bitcoin drops to zero.
Now the price will crash and those stolen bitcoin aren't worth anything now anyway.
The reason why Bitcoin has it's value is because of Satoshi's original social contract that we have all bought into, changing a fundamental rule would undo all the faith the market has in Bitcoin and is suicide.
Satoshi never said that a Government isn't allowed to buy up all the bitcoin's, so that is ok and in line with the social contract, but Satoshi said that the private key is always required to send bitcoins, any movement of bitcoins that does not involve the private key breaks the social contract and thus removes all faith in the system.
That is my assessment of the situation.
