From what I observed of the greys, including Fore's observations and personal experiences, was their goal-orientated strategy. There is also the factor they are an artificial lifeform (more specifically, they are a biological robot, a biomechanical machine.)
We only need to look at the military usage of drone technology on earth to ascertain that when an asset is lost, we don't go looking to rescue it. Furthermore, crashed/inoperable hardware is abandoned. It is only when it is an asset in a workable state, that intervention occurs, usually in the form of the destruction of the device/vehicle concerned. This is the human military goal-orientated mindset, money is not an object, the goal is.
I'll now point out an observation I made of Fore's encounters. With the Pleiadians, they seem to have a hands-off strategy in general, and have a non-interventionist mindset. Unless it is a project they are directly or indirectly involved in.
The Greys are goal-orientated, and this extends to intervention when it is necessary to achieve a goal. If this means intervening to ensure a subject will have enough money, then they will do so.
It is notable the Greys taught Fore Money making techniques, but I did not note the same of the Advisor. However, they Greys also seemed critical of gambling, as it would cause alterations to their overall operating model which was highly disruptive.
[I occasionally buy a Lotto ticket, with the hope that it will one day win and cause serious headaches for certain individuals.] My thoughts are they are grown and created to purpose in general, with little ability to move outside of their designated parameters. From my perspective, the third-party operating them considers them expendable, and will not intervene if something goes wrong with the sent-out equipment. I suspect the third-party is unable to physically appear on Earth.
I have observed a Hammerhead Alien in encounter gear once. Based on what I have read of others encounters with them since, they have the ability to "pause" an individual, full memory control, and very little I can say about them as a result. I only knew the individual existed because of my sudden awakening and a flash of green light. However, being sly and educated, I realised the image of what had been there would still be imprinted on my retina for a time. So I carefully examined the afterimage, and realised it was something very new, and very unusual. These are creatures of stealth, they ensure their subjects will never know they were there. However, it is clear they are not perfect, and I suspect they have a degree of arrogance which causes them operational problems. I would expect them to ensure nothing was left if they lost an asset.
In most cases, I suspect the encounters are with biological encounter suits, which places different considerations as a lost asset is not a lost "person". In some cases, that means that an asset of importance may warrant intervention to retrieve or repair it.
With technology, I suspect that there is nothing new on their vehicles or devices which we don't already know, they just happen to use our technology in a very different way which is non-obvious to us. As a result, anything we seem to gain from a piece of their technology would be considered to be within the parameters of our development. The other observation is that by the time we work out what something advanced does, we would have had to have developed the technologies to make it anyway.
A more sinister side of me suggests that lost technologies are intellectual property of the ones losing it, and anything we derive from it places us into a technological debt which we must pay back to them. What form that takes, would most likely be a very alien concept to us; pun intended.
