Every launch has to account for de-orbiting and debris avoidance. In this case, satellites will be intentionally de-orbited when their Krypton fuel gets low and they can no longer station keep. The Starlink site has a quick blurb about it: "Starlink is on the leading edge of on-orbit debris mitigation, meeting or exceeding all regulatory and industry standards." "At end of life, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event the propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years, significantly less than the hundreds or thousands of years required at higher altitudes."
