I don’t see “about 10 years”, I see “decades or longer”.
10 years would be a miracle, there’s effectively no atmosphere above about 600km (which is one reason the other mega constellations have been at or around 500km)
Except what they deliberately deorbit (which they’ll probably be trying to do, if only to avoid fouling up their own orbit) they’re going to generate debris which is up there for centuries, realistically
