booster was low on fuel, plus no mood of risking tower with boom, boosters are cheaper than towers.

Slight underperformance in the engines resulted in the the booster not reaching where it was supposed to be and the GNC systems automatically aborted to the gulf for safety.

Two reasons floating around. 1.)They lost communication with tower 2.)They ran out of fuel for safe land.

Do we know what sea life just died as the booster exploded? What are the impacts to the Texas Gulf when a booster detonates into the ocean?

"Slightly low on fuel."

If I understand correctly, the margin was tight enough not to take the risk of damaging the tower.

Apparently the booster signaled it didn't have enough fuel to risk it. Either because it consumed more then expected on the way up, or a measurement error potentially.
