Why is the show coming to an early end?
It might have something to do with money.
As insiders toldDeadline, most Netflix shows have a run of around 30 episodes or three seasons.

“I’m grateful to Netflix and Sony for supporting me in this decision.”
Morgan previously said that he had no intention of allowing the show to run into the modern era.
“I feel uncomfortable writing about events within a certain time period,” he toldEntertainment Weekly.

Because it’s too close to the moment."
