The article phrases this weirdly, but they are talking about the 40,000 Starlink terminals in Ukraine that Eutelsat is trying to match, not about LEO satellites.

Eutelsat's oneweb subsidary currently has something over 500 satellites in LEO orbit. I think starlink has over 7000. I don't know much about all of this, but I assume if it just about covering ukraine they won't have to match the 7000 starlink satellites. The whole situation might open a opportunity for oneweb to catch up with starlink.

The number refers to the ground terminals not satellites.

Eutelsat already has global coverage. So coverage is also the wrong word to use.
