No cloud! Too expensive! (my opinion comes being a brief stint as a contributor in data taking for the CMS detector at the LHC. Accelerator ran, threw off data, which went into storage for ad hoc analysis by project collaborators; all data released into the public domain and freely available)

So-called "close" SETI looking for emitters in our outer solar system.
From rational point of view (history of Indians, general history) and philosophical point of view (great filter) it is safer to keep quiet.
A lot of scientists got killed by their own inventions. And active Seti should be banned since very few can bring doom on others - without even asking them if they agree for that. Did anyone from the active seti community ask for consent? Nope. They know most people would be against it. UN and governments should be too. Although if they were some assholes would start doing it just in spite.
“The universe is a dark forest. Every civilization is an armed hunter stalking through the trees like a ghost, gently pushing aside branches that block the path and trying to tread without sound. Even breathing is done with care. The hunter has to be careful, because everywhere in the forest are stealthy hunters like him. If he finds other life—another hunter, an angel or a demon, a delicate infant or a tottering old man, a fairy or a demigod—there’s only one thing he can do: open fire and eliminate them. In this forest, hell is other people. An eternal threat that any life that exposes its own existence will be swiftly wiped out. This is the picture of cosmic civilization. It’s the explanation for the Fermi Paradox.”
That's a very tiny window in time, and after that the bulk of the comms goes optical or to satellites using far lower power levels than your typical radio or TV station. Ironically the first thing ET might be able to hear and what we might be able to hear from ET's is "CQ CQ ... ".
