They should prove those speeds before I believe them.
I'm weary of more incompatible internet megaconstellations, especially when this one has the money behind it to actually launch.
I don't understand why Blue and Amazon both have constellations, or why the Amazon one couldn't have added a MEO optical backhaul layer, or how an "enterprise" focus actually differs from what Starlink already offers or Leo will offer. I suppose it's just a faster version of what Oneweb is doing.
