How can this be, if he got all the stash at the premine ?
He didn't. I don't know where you heard that.
Then who got the 2 million DASH mined with the buggy code in 48 hours ?

As to "many people were mining at that moment" is doubtful:

Yup that scumsucker cost most of us days while secretly mining And then changed the reward to mak his insta/Pre-mine worth even more.

And of course when they went back on their word of a relaunch they provided a functional wallet when it was too difficult to mine.

And of course win client pools not working when it was impossible to solo mine.

And the difficulty lie gets caught

In on the scam from the start.

And here's a safe *cough compiled win version (from some Random russian: name translates to "I got TK'd" I thought that was amusing at least) for those that can't recompile the late win code for the first fork

And thats just the start of the second relaunch.
The shit just keeps rolling downhill on those morons that kept trying. The true believers did nothing but keep the network secure for scraps that didn't pay the lectric it cost.
