They got too many tokens before the actual launch into PoS.

Nobody thinks that a normal company should give most of their shares away to people who do nothing for it. That same principle should be applied to blockchains, too.

This way they control most of the system, hence they can even sensor people.

Because this is built on a blockchain, nothing can't be censored.

Also Bytemaster, aka Dan Larimer scammed the BitShares users countless times in many ways and created a financially stupid DAO/blockchain

This is just bullshit. Bitshares 2.0 is perhaps the best DAO so far. The biggest problem with it has been too much low-quality shareholders who don't understand how it is supposed to work.

As we have seen with Steem, Dan can design very fine blockchain when he has a good team and no opposition from other shareholders (because he and his team has the majority of the shares).
