Implying the founders are keeping 100% of the 80% premine is disingenuous in and of itself. You condone lying too? Most of it is being given to people who register new accounts on Steemit.
No cryptocurrency is decentralized, as Anonymint will be happy to explain to you (or at least link to the 100 page thread where it was proven). Yet, all of them use the buzz word decentralized in advertising materials. If you support any other cryptocurrencies, and I am assuming you do since you're here in the first place, then you are being a hypocrite with this point too.
I think there are two ways to see this
1) As a cryptocurrency investor
You see steem has a lot of stealth/pre/instamine (no idea what happened at the start) for the owners and you don't see that as good for investment or as a positive trait for a cryptocurrency
Others see it as a very good investment regardless and want to invest.
2) As a social network user.
In a sense, Steemit is more of a social network / platform, than a currency.
So as a user: Do I care about how many shares Zuckerberg has in fb? No. Am I getting paid in fb? No. Am I getting paid in steemit? Yes. Do I need to care how my money was generated and given to me? No. Do I need to keep "steem" or "steem dollars"? No - I can dump them right away - with the exception of SP which gives 1/104 per week. In any case, it's money you never had, and you are now making and if it is improving your life, why not.
So there will be this "clash" of perspectives between (1) and (2) - because (2) don't care and they will outnumber (1) pretty quickly. And the criticism of (1) will be irrelevant to group (2) as they have different starting points, interests and profit vector. One wants to put money to make money but is afraid of "the scam", the second comes and writes content to get paid out of nothing. There is not much overlap in what these two groups "see" in steemit.
