Scientists don't want to just go ahead and say there's life on Titan. That'd upset too many applecarts.
But they do want to puff up public excitement, so an increasingly poor proletariat will be excited enough to willingly ship them billions to pursue their hobby. And keep them from having to try to get jobs at McDonalds.
It's a tough task, entailing as it does trying to convince breadwinners to make the choice which child to starve on behalf of notional Science - in a politically-managed economy that right now is working hard to squeeze still more blood out of their stones with a slew of new taxes and regulations designed, like all the other ones, to make the powerful rich richer.
Thus this balancing act.
Is there life on Titan? Or Mars? I have no idea. What I do know is that what we are told depends completely on the political (and economic) interests of those who do the telling.
We have no reason to believe we know what really goes on in our world, much less on others. We may even be ignorant of basic laws of physics - or "know" things that're wrong. That's the whole reason there's such a thing as classified information.
