I'm sure in some cases it's not that they fear SETI, but that they would like it's funding, so discrediting it might do the trick.
Although, there are some that fear we may find hostile advanced alien life and alert them to our existence and location.
I totally disagree with that.
An advanced civilization would understand the folly in aggression.
It's always counterproductive in the long term.
The cause and effect universe that we all live in makes that so.
If a civilization is able to get here, they would have been aware of us long before they were able to make the trip. So, if they were aggressive, which I seriously doubt, and if some UFOs are the real deal, they would have made their move upon arrival.
They could easily wipe out all human life while leaving everything else intact.
We're still here, so if any UFOs are real, they're obviously not aggressive.
They could be autonomous, or semi autonomous research probes, or "manned" by scientists.
The only threat they might pose would be cultural or biological, and I'm sure they would be conscious of that too.
I really don't think there are any Klingon types with their sights set on Earth out there.
