No, EOS is talking connectivity from the ground. Check the announcement of 30-Sep-2020. Below is an excerpt:
The EOS technical approach uses a special, laser (called a guide star laser, see image below) to measurethe distortion caused by the atmosphere. An equal and opposite distortion is injected into theoperational laser beam (e.g. a communication laser) at its source. Consequently the atmosphere actsas a correcting lens to restore the laser beam to near-perfect quality as it moves through theatmosphere and into space.

Using this technology laser beams emitted from the ground can now be manipulated in space as if theatmosphere was not present. The previously unavoidable loss of laser intensity can be largelyovercome and the negative impact of atmosphere on the laser can be ignored for many applications.

In practical terms, laser intensities achieved in space can now be 1,000 times higher, using the samelaser. For many space applications, the laser power required in the absence of this technology wouldbe prohibitive.

Well no... cloud cover and precipitation interfere with optical communications. I'll write to EOS Space Communications and warn them to avoid building their downlinks stations in cloudy or rainy places. It'll save them a fortune, although the president of Melbourne might be angry about missing out.
