Oh no! Another alien probe

[Succubus]

From the article:

Oumuamua might be shaped rather like a needle, up to 800 meters long and only 80 wide, spinning every seven hours and 20 minutes. That would mean it is like no asteroid ever seen before, instead resembling the collision-minimizing form favored in many designs for notional interstellar probes.

I would think the fact that the thing is spinning would suggest it is not under any sort of control. And as for it being of a 'collision-minimizing form' that would only work if the pointy bit is facing forward. If it looks like a rock, acts like a rock, then its probably a rock.
It's a pity we didn't spot the bastard a few years ago then we could have built a probe to chase after it. A close up study of an extra stellar object, now that would be mightily interesting.
