Which is utter bullshit. Quite painful to hear too. LEO is not your average american homeless stolen mart cart. Can we please rise to some more insighful level of discourse?
Collision risk is significantly reduced by having maneuverable spacecraft with good conjunction prediction systems in place. But fundamentally, nothing is perfect and accidents can and do happen - you set a maneuver threshold based on an expected collision probability, but it's an engineering tradeoff: "spend the fuel to maneuver out of the way of everything, no matter how remote, or accept a small collision risk?"
And of course, when you are launching thousands of satellites, you will have a few failures that will become unmaneuverable hazards. Just the way it goes, you can't realistically engineer your way to perfect reliability.
So sorry, I have to reject your claims that it's "utter bullshit." Space debris risk is a well studied field, so much so that satellite insurance companies are starting to fold those calculations into insurance premiums. So yeah, it's real, and it deserves more than a pithy dismissal.
Not saying it couldn’t be bad if there were such a collision as obvi a really bad collision could in the short term damage Starlink and anyone else who decides to use that orbit, but this isn’t existential risk territory anymore.
