Arstechnica had an update article on the harvard scientists paper:
Predictably, online media go nuts over ‘Oumuamua and Harvard scientists':

I would posit a few things in this kind of debate (that i normally would steer clear off).
1. If it was an alien probe, why would it behave as 'strangely' as it did? If you want your probe to remain unnoticed you'd probably do a better job of making it do just that.
2. If it was an alien probe, and they wanted us to know it, why go to the trouble of making it seem like it could be a natural (but unusual) object?
The only other option i have is that it is some kind of test, to gauge our re-action (which with a lack of space ships would rely on them listening to our communications, and being able to filter out everything except the stuff on oumuamua, which would be difficult probably?) or it really was just a slightly freakish natural object like we have not seen before, like a real 'anomaly' that you'd get in a fun sci-fi series etc.
