I am - I've used their products. I don't think you realize how expensive their products have been historically. These were govt / large industry class products. They had a market because of carriage requirement and govt contract. ie, large container ships could only use certified products and these guys were only products out there. This all may have changed (I'm 6+ years away from details). And no - these large players generally have not needed to use optical space links - they are much higher orbit so can downlink on land in almost all cases.
