It's nothing yet except for a statement of intention: we aspire to become the next SpaceX and hope to raise the interest of investors that can't access SpaceX stock. There is no talk about the engines, it's quite clear that the Rutherford won't cut it (Electron already uses 9 of them). So they have to either buy or develop an engine, expensive in time or money.
The mega-constellation sweet spot argument is not really convincing, if you have a reusable mega rocket with a relightable second stage (like SpaceX plans), you can hit multiple planes in a single launch. The 8 ton class is probably just the largest they can afford to plan at this stage.
