That has nothing to do with regulating the initial distribution of a digital currency. Evan was fully within his rights to determine how Dash would be distributed, and furthermore, make changes in the future. He could have premined it 100% and sold the coins for $1000 a piece, and it still wouldn't be illegal. It's obvious that you're grasping at straws.
And, ANYONE can make any changes to the code (including emission adjustments), it's up to the miners and peers to download and agree to the code change.
You realize that Dash at that time, was
closed-source. The only one who could have made changes to the code was the developer(Evan Duffield). Couple that with the fact that he was able to mine so many Dash(We can also infer that his hashpower would have been high during that time), and he should have been more than able to implement any changes in the code and get it accepted by himself alone.
