Fine theories, but how does it relate to actual data they got?
That article did not relate any of the theoretical speculations to any measured data. This just seems to be a plausible scenario that fits the general facts of the current methane situation on Titan. Is this theory testable? How many other theories potentially fit the same facts? How strong is the evidence supporting this theory or is it just some simulation scenario that seems to work?
Anyway the article spawned more questions in my mind than it answered.
