Again you are stating as fact that the coins were "distributed among the community". It isn't fact, it is speculation or opinion. Nor is it a "fact" that the instamine was accidental, although you certainly may believe it.
What is a fact is that we know that one person (an insider) now owns 11% of all the coins in circulation (almost a third of the instamine), which were either instamined directly or purchased directly from someone who did, and not out of broader "distribution". At best, "some" of the coins were distributed. But neither you know nor anyone else knows how many, to whom, and where those coins are now.
Adam is right that it is totally off topic and another diversionary tactic to draw attention away from Dash's instamine, but since you asked
https://forum.getmonero.org/20/general-discussion/211/history-of-monero
which shows a graph of the early mining hash rates, the optimizations that were done, and has specific links to more details.
Now compare that with this
https://dashtalk.org/threads/the-birth-of-darkcoin.162/
which has no graphs or numbers or specifics at all. There are no links to original sources. It doesn't even acknowledge that 500K+ coins were mined in an hour or almost 2 million in a day. It just says "but none of us realized the amount of coins that had been issued at the time" which is at best a half truth (and probably not even that since you can easily see the coin supply from the node directly, you don't need a block explorer), since at the very least people knew how many coins they had themselves mined, and it was a lot.
