Gregory's ServerFor the most part YES. Most of these satellites have ion thrusters which should allow them to be deorbited on command. The orbit these are on will also naturally decay after 5yrs if the satellites stop occasionally boosting their orbits.
This is all a bit uncharted air control problem the so it's probably a bit dangerous to bring a lot down at once.

Yes, they will mostly burn up in the upper atmosphere and are unlikely to kill people via direct impact. However, these large numbers of satellites will deplete the ozone layer and kill and blind people via increased rates of cancer and cataracts.
The chances of SpaceX/Elon Musk caring are ... I dunno ... close to zero. Even if government regulation demands that they do something about it, I expect they will simply defy the law.
