They've gone for a large constellation of small satellites with short lives, which is a set of design choices that all feed into each other.
Satellites are traditionally designed to last for a long time because they're so expensive to launch. As such they're also expensive to make, and it's slow to iterate on them.
Being in low-earth helps the launch cost (on top of the existing SpaceX advances). Putting out 60 per launch helps too.
