These satellites are in geosynchronous orbits. The minimum latency of an interactive exchange with something on the internet is a major fraction of a second. One might think of something like ssh being almost perfectly unusable, and it is, but consider how much back and forth there is with web pages being rendered these days.
Having lived with synchronous satellites for a couple years I'm here to tell you they absolutely stink for much beyond watching streamed content and downloading files.
Something like Pi Hole to avoid wasting time with junk would be valuable in this setting and doubly so if Pi Hole's name server caches effectively.
The basic principle involved with these services is statistical multiplexing with a constrained composite link speed. Translated, that means the more subscribers there are the less bandwidth during busy times. So although Hughes touts up to 100mbs down you won't see that unless you use the system when most are asleep.
Finally, if this system is truly advanced it will support alternate ground stations. Without that you get the astonishing experience of blackouts when thunderstorms visit the ground station.
