Do you mean the most important thing for SpaceX? Because it's also important for Ukraine not just to win on the technological front but also to seem like they're winning, and bragging about capabilities helps their propaganda effort. "We have a network you can't easily disconnect or jam, and your invasion is being livestreamed on YouTube right now" might even have the effect of discouraging some war crimes from happening. If there's even a slight positive impact it's worth it.

I hope these network terminals get used, but the messaging is important too.
