I'm not sure there's that much chance for profit even if you do find aliens, at least not directly from the information you'd get from the aliens. These aliens would be many light years away. (absolute minimum ~5, right?) So for a long time you'd just be receiving signals (because it would take at the very least 10 years for your first message to get to them and them to respond).
First of all, the signals you'd receive would probably be worthless. Even if you manage to understand them despite the fact that they likely use some totally different language and encode information in radio waves in a different way, it's not like we frequently broadcast "this is everything you need to know to build a computer" or anything super-useful. There might be some useful mentions of science they've developed (the equivalent of our NPR science programs), but it probably wouldn't be in enough detail (especially since their lay people would presumably have a much more advanced scientific base if they're so far beyond us) for us to really get anything out of it.
In the meantime, people have probably heard that you got alien signals, and they'd eventually figure out how to receive and decode the signals too. Maybe you could patent it or something, but again, if they're far enough away, your patent might run out before you do much with it. You'd get somewhat of a head start, I guess.
And since this whole thing would take so long to cash in, and your investors took an absurd risk, they'd expect at least 1000x on their money.
If there's life out there, we'll probably find it eventually.
Considering life is a binary condition (there or not there) and we haven't found anything to strongly indicate the odds of life existing elsewhere are very small, I certainly wouldn't call the odds of finding life absurdly bad.

That's quite possible, but you'd want a highly-advanced technological organization - some bacteria-type things in Martian ice would be a scientific breakthrough, but unlikely to be massively profitable.

I don't know. I would like to think that this is so, but it seems hard to reconcile with the Fermi paradox (referring to intelligent life, at least). We do not know the probability of intelligent life developing, but I consider it plausible that the probability is such that although other life exits, it is beyond the limits of known methods of communication (e.g. extragalactic).
Yes, this is possible. I'd argue though that if 2 instances of life exist (them and us), n instances must exist, (and thus some must use radio waves) because it clearly demonstrates humanity wasn't a freak septillion-to-one occurrence that shouldn't have happened.
Interesting point, but given the amount of randomness involved in evolution, the physical complexity of cognition, and the timescales involved, is it possible that even given massive numbers of cognitively advanced species in the universe, each could have such a fundamentally distinct ontological relationship to reality and model of the physical universe that even a concept as seemingly scientifically basic as a 'radio wave' would be unique to us?
This would be relevant for civilizations like ours, using waves to purposedly contact with others, but not for signals used to communicate with spaceships or colonies of the same alien civilization.
"We've searched dozens of these floor tiles for several common types of pheremone trails. If there were intelligent life up there, we would have seen its messages by now."
I suspect that they communicate in ways that we can conceive of, and have recently started to communicate, ourselves.
Specifically, if you're broadcasting radio or TV signals that look like anything other than random noise from the perspective of an uncorrelated receiver, then you're wasting energy. Human history suggests that there's a window of about 100 years between the time when a civilization learns RF theory and starts to generate coherent signals, and the time when they learn information theory and stop.
I've been thinking about faster-than-light communication recently.
Consider gravity. Is its effect instantaneous? That is, gravity varies as the inverse of the square distance between two bodies. If, say, the Earth were to suddenly get much closer to the Moon, would that gravitational effect be "instant"? Or does it propagate at the speed of light?
If gravitation is somehow "instant", then one could imagine an apparatus which allows you to transmit information instantaneously. (You would need a way to measure the effect of gravity from the sending body; perhaps by measuring the height of waves formed in a planetary-sized sphere of water.)
Instantaneous gravity exists in Newtonian mechanics but not in modern theories. Gravitation is thought to be transmitted by gravitational waves, which have a finite speed of c. It is not possible to transmit information at a faster speed than light in special relativity.
Gravity propogates at the speed of light. However, using gravity to send information will allow you to send information through most objects like Earth or the Sin without any satilites to redirect it around the object.
Just knowing something is possible is invaluable. "Our space-scouts returned from 6 light-years away yesterday, validating govt funding of this 2-year-old program"
