Read the rest of the little tit's tweets. It's one long line of bitterness and FUD. And don't you think you would've heard something about it in a rather loud manner on every single thread on every single bitcoin forum and news source if it were true?
Is this even possible to shut down whole system by anybody?
you know that bitcoin is decentralized? no one can forcibly shut down anything, that's the point of a decentralized system, totally detached from anyone
the OP is referring to the forum btw
You are both wrong:

It is posts like these that I don't particularly like, people stating facts about Bitcoin that seem true, others see them and also believe them, yet they are furthest from the truth and the answer was already posted in the thread. This is the reason that people like patio11 exist.
FTFY
That's usually what is meant when someone says "impossible to shut down".
If you want to forcibly shutdown the bitcoin network temporarily, you can do so with a 51% attack, a Sybil, or exploiting bugs/exploits in Bitcoin Core (which is arguably what the March 2013 issue was, someone could've exploited the situation to double spend coins, IIRC OKPay had a transaction double spent). It is incredibly difficult to do, but it is POSSIBLE, and those who say otherwise are misinformed.
51% isn't shutting down, it's just a cintrol over the network, if you stop the attack the network will return alive
let me rephrase it, it's impossible to shutdown bitcoin permanently
