Where is the blog post stating this was a pre-planned scheme to raise money from investors to pay for development?
Here are hundrends of them https://bitcointalk.org/index.php?board=159.0
I can't see how coins like Litecoin or anything else, falls under a different category, maybe the "Chinese guy" that launched/created Litecoin will get away because he didn't use any of his "premined" coins for development, lol
or maybe because he kept the "development part" a secret, I'm sure they will ignore him! 
In fact it doesn't even raise money for development. One of the big issues with BTC has always been how to pay for development.
That's only one "interpretation", my intepretation is that the btc development is paid by the success of btc and by those that buy btc.
In the end of the day the only difference between Steem and every other crypto is that some miners believed in the project most than others and so they mined the most coins, they can do whatever they want with those coins, no exceptions.
