Several species of alien seem to be involved as well and it all appears to be scientific research of some sort. Actual evidence of physical changes in the individuals has not been forthcoming at all. at best we have clear reports of sample taking and some induced mating which is as close as we get to interactive activity.
The specimens are not obviously harmed, although that is not entirely true either. They are often shaken up. Actually the narrative is uncannily similar to how slaves were treated.
One issue though. The lid of secrecy went on this all back in perhaps 1950 at the latest. We have had only leakage since then and early technical work still outside the defense industry. That adds up to 65 years of secrecy for no good tangible reason except to provide a serious march on all those not invited. this has actually hampered innovation in many areas.
The cult of secrecy killed off Chinese research over two thousand years ago and it did not shake free of all that until the west arrived. The same held true elsewhere as well.
I do suspect today that the USA has huge gravity space ships tasked for space bombardment of the planet and likely effective UFOs of their own as well. Talk about holding the high ground..

“If it does indeed turn out that there is relevant physical evidence, if this evidence is carefully collected and analyzed, and if this analysis leads to the identification of several facts concerning the UFO phenomenon, then will be the time for scientists to step back and ask, what are these facts trying to tell us? If those facts are strong enough to lead to a firm conclusion, then will be the time to confront the more bizarre questions. If, for instance, it turns out that all physical evidence is consistent with a mundane interpretation of the causes of UFO reports, there will be little reason to continue to speculate about the role of extraterrestrial beings. If, on the other hand, the analysis of physical evidence turns up very strong evidence that objects related with UFO reports were manufactured outside the solar system, then one must obviously consider very seriously that the phenomenon involves not only extraterrestrial vehicles but probably also extraterrestrial beings.” (source)
