Until there's an instamine permanently marked on the front page of the dash page, it would not be good for new and incoming investors to not know what they're getting into--do you have a problem with new investors knowing Dash's past?
Your concern for "incoming investors interests" is touching. I'm sure exceeds your concern for your own.
I'm sure once they have all the facts, they'll use Monero if their main concern is privacy and decentralization. But why would you want to hide the instamine from the Dash front page? If your claim that it doesn't matter is correct, it would save you a lot of time and silence the instamine critics forever.
