Like I said its fun times when we see something occurring and "<shrug> aliens" is equally as possible as anything else... possibly better.

I agree. But a very thin very low mass object with a large surface area acts very different than a solid asteroid. Read the link I posted . Solar radiation may be causing it to act as a solar sail. Without outgassing it is difficult but not out of the question to be accelerated radially. Remember two accelerations are occurring. One towards the sun and one tangential to the sun. Radial.
Outgassing as a viable explanation of Oumuamua acceleration excess
https://space.stackexchange.com/ques...eration-excess
'Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the Solar system. Recently, Micheli et al. (2018) reported that 'Oumuamua showed deviations from a Keplerian orbit at a high statistical significance. The observed trajectory is best explained by an excess radial acceleration Δa∝r−2, where r is the distance of 'Oumuamua from the Sun. Such an acceleration is naturally expected for comets, driven by the evaporating material. However, recent observational and theoretical studies imply that 'Oumuamua is not an active comet.
