This is not for the people by the people, you are all brainwashed into thinking some random dude just made this currency and that its not controlled by anyone! I bet mtgox had everything to do with making bitcoin. That is why we don't know whom the original creator actually is because if you knew, you wouldn't use bitcoin!
Trademarking a word is something anyone could have done. That does not give the trademark owner any more control over the network than you have. Bitcoin is a math program and does not listen to anyone.
You can't copyright the cryptocurrency idea, the best you could do is patent a mining style (Such as but not including PoW or PoS) but there would't be much you could get in return from trademarking it. Plus people could copy it, they'd just have to modify 30% of the code, depending on where you live.
Mt. Gox was originally "magic the gathering online exchange", and had no roots in Bitcoin. They just discovered bitcoin needed an exchange, and as such, they made one.
Lots of people are claiming domains with "Bitcoin" or something related to it in it, it's because they got in on it first and took the domains for themselves. First come, first serve. Just because you didn't get a domain to sell for $1,200 doesn't mean everyone else is a scumbag.
And stop complaining you didn't get in on it at first, when whole Bitcoins were $2. And there have been plenty of threads related to THE MOST LIKELY reasons Satoshi disappeared, and your claim is not one. And it isn't even that plausible.
EDIT: TL;DR It's decentralized and there's evidence proving it is.
