Yes, starlink gives an additional choice, and that's great, but this approach is even harder to enter than laying down new fiber.
Actual solution is to require last mile to be leased to any competitor. This was the reason why there was so much choice with DSL in early 2000 (Title II which applied to land lines had this requirement).
"My client, who has to remain anonymous for obvious reasons, wants you to break into this facility and fire the space-laser at the targets stored in this drive."
"To deflect attention, you are to pose as cyberterrorists for the duration of the mission."
It would only take one innovation in space propulsion, and I could easily see fighting over space real estate leading to the destruction of satellites.
Starlink seems particularly vulnerable, with the satellites lined up like dominoes.
(It has occurred to me that Starlink might secretly be a Brilliant Pebbles installation already, waiting to be revealed as such if a major war were to break out. However I believe the thrusters on extant Starlink satellites are too weak for this. And they don't have the sensor suites for it either, at least officially.)
It is very plausible that the US government (Space Force, NRO, NOAA, etc) might sign up to provide some of those additional payloads. Although surveillance technology is much more likely than active weapons systems. I think SpaceX will likely resist turning Starlink into a weapon, it could be bad for their corporate image and might cause political difficulty with Starlink's approval in some countries.
Surveillance technologies can always be covered up as commercial imaging, environmental/scientific imaging, military communication systems, etc.
