It was the only ending where anything really changed for the better. HELIOS still needed the cooperation of the people to get anything done. That ending of the game ended with HELIOS issuing a bunch of eviction notices (and locking doors) and arrest warrants. People decided to go along with that.
It was clearly a better ending than the one where everything went back to the stone age and 90% of people immediately starved to death.
I always did think the HELIOS ending was the happiest one in Deus Ex.
