That is a positive assesment. On the other hand, imagine if the aliens think that the senders of these probes were deliberately sending pathogens to the aliens' worlds. This is a statement of war.

Nematodes manipulated evolution to produce organisms that would send them to other solar systems.

Alpha Centauri aliens who'd be able to detect and intercept that probe would have their Twitter flooded with funny memes made from our hn discussions of the mission long before the actual probe arrives. Actual arrival wouldn't even make it into their news.

We couldn't intercept ʻOumuamua and it wasn't travelling at a high fraction of light speed.

Actually capturing an object with that much velocity would require a high level of sophistication, very fast reactions, and a big energy budget.

If they had our level of intelligence, probably.

The prospect of aliens trying unsuccessfully to communicate with a nematode is pretty comical
