Still new - but apparently the FCC (Federal Communications Commission) submitted filings to the ITU (International Telecommunication Union) to arrange for 30,000 more satelites on behalf of Starlink.
The FCC released warnings a few days ago reminding providers that they must comply with the Emergency Broadcast System. Is this wishful thinking?
Wouldnt really work that way. Starlink is just an internet connection like ATT, Comcast, xFinity, Charter, Spectrum, Centurylink, etc.
If he really wanted to send out a message there are other "official" ways. He'd probably use Parler and Gab first though.
