If this support claim is true, it is not for the purpose of direct public internet connection. As many people have already pointed out, for this, the Ukrainian people would have to have the necessary devices and software, as well as subscriptions.
This may be accomplished in the later stages, but if the news is true, it will probably provide the broadband connection need of the Ukrainian state in case the Russians damage the possible fiber cables in the first place. Then, if the war goes on, in the following stages, the device is first distributed to strategic people and institutions (by Elon and the USA), and then it may spread to the public over time.
that is, in this way, in case of a possible attack by the Russians on the Ukraine's internet network, the country will maintain its connection with the world by backing up from the skies.
