Terrestrial alternatives beat out the Little-LEO cell phone constellations proposed during the 1990s. Why shouldn't terrestrial alternatives also beat Little-LEO at this broadband internet service game? - Ed Kyle
Long endurance US eg ACES, could be used to deorbit any dead satellites. Use a cubesat to find and latch onto dead satellite, and maybe preposition it for easy pickup by US. The US would pick it up next time it delivered satellites to that orbit.
SpaceX, at least, intends to retire the satellites (planned obsolescence in 4 years) much earlier than current satellites which are basically run until they stop working or very near to that point (10-30 years?). That alone should dramatically improve odds of successful disposal.
Really long watchdog (say 2 months) and independent deorbit system? Or launch with each batch a dedicated SEP deorbiter?

A more powerful engine and bigger fuel tanks would allow the cubesat to do the deorbiting itself.
Boeing's FCC filing is here:http://licensing.fcc.gov/myibfs/forwardtopublictabaction.do?file_number=SATLOA2016062200058...On the orbital debris front, they are reserving 90% of their propellant to lower each satellite to an orbit below 500km and 5-year lifetime at end of mission....
Today’s report from Bloomberg on Apple’s latest high-profile hirings includes a passage that sheds light on Boeing’s alleged talks with Apple regarding a broadband satellite service. According to Boeing’s regulatory filing, the aerospace giant is planning to blanket the Earth with more than a thousand satellites providing fast Internet coverage throughout the United States and internationally. According to authors Mark Gurman and Mark Bergen, Boeing has talked with Apple about investing in or partnering on the project.

The filing in the previous post is for the 2.956 satellite constellation that Boeing filed, which shows a similar set of orbital inclinations and deployment schedule as the SpaceX constellation, which Wyler has been disparaging.Boeing also has another V-band constellation filing (SAT-LOA-20170301-00028) for a smaller number of LEO satellites along with some inclined GEO satellites.
