Easily verified through Verizon's Looking Glass.

We all know Verizon's BGP routing is a disaster, but does anyone have 
any ideas?

Looks like chinanet is the routing disaster.  But over Lumen I can get 
to Baidu's 182.61.254.169 IP when tracerouting to 182.61.254.1.

I think the original thought was that the satellite service would be used in
rural areas and 5G in cities so there'd be geographic separation, but Starlink
is selling service all over the place.

Pretty much, with the addition that 10900 MHz to 12700 MHz has for a very
long time been historically reserved for Ku-band one-way and two-way
satellite data services talking to geostationary satellites.

The only thing that SpaceX is doing new here is talking to moving LEO
satellites with their phased array terminals.

Adding a terrestrial transmitter source mounted on towers and with CPEs
that stomps on the same frequencies as the last 20 years of existing two
way VSAT terminals throughout the US seems like a bad idea. Even if you
ignore the existence of Starlink, there's a myriad of low bandwidth but
critical SCADA systems out there and remote locations on ku-band two way
geostationary terminals right now.

The article is super light on technical detail but I think what
they're saying is:

The 12ghz spectrum has been allocated to satellite services which have
very low power signals at the receiver. Both SpaceX and Dish have
bands within 12ghz. Dish has asked for permission to use its 12ghz
spectrum for 5G which has a relatively high power terrestrial signal.
SpaceX is calling foul: the spectrum was allocated to low power
satellite signals and high power signals don't play well near low
power signals... particularly when a bunch of the transmitters are
cheap consumer equipment that may bleed some of that power into
adjacent spectrum.

Now someone with more knowledge please tell me how close I got.
