The problem, in my understanding, is that the drone ship currently passes the video data to shore via a link to a satellite in geostationary orbit. Because the drone ship's dish has to be aimed within a very tight arc in order to communicate with the satellite, the vibrations from the first stage's landing burn causes the connection to be lost. Because there'll be a ton of Starlink satellites up there once the constellation has been completed (and they'll be much closer than geostationary), the acceptable arc for the dish to be aimed should become wider, and it will likely become possible for SpaceX to use the Starlink network instead and maintain a good connection the whole time.
