Those witnesses represent the entire community and not just a part of it since they were voted by most of the votes and stake.

I partly agree, but in the end only a few very big accounts (from which @freedom is completely unknown) decide which witnesses are on top.

Now, in respect of his available STEEM power, @justinsunsteemit is the 'new @freedom' and teaches us that there should be means (implemented into the code) to restrict the influence of single individuals, if we want STEEM to be decentralized.

I think that at least we should reduce the number of witness votes per account to lessen somewhat the huge influence of the biggest stake holders.
