If the good aliens incapable to give us even blue prints for those two mentioned tech, well they just wasting our time and try to mislead whole farsight community.
Why i think we have right to demand such tech?
Well , if we humanity somehow theirs close friends and or relatives from other alien worlds, than it its obvious they must help us ! (that what good aliens told Courtney)
Courtney say, they dont want to disrupt bad aliens, because then bad aliens would retaliate, but i say with all common sense, this decision is not theirs , but its ours we have right to decide when to attack bad aliens!
As result, we should be suspicious about "good aliens", they are here at least like 12 000 years , they have lot and lots of time to develop a strategy plan for helping us ,but what we see, they think our political leaders are corrupted and military incapable for any sort of negotiations because of influence of bad aliens.
They think they can do disclosure by talking to small groups of humans and through them reach big numbers of mass population on Earth?
They 100% wrong, people on Earth most time not interested in such topics , me myself i am "initiated" in secrecy long before i was an adult, i have a whole military legacy dealing with this crazy stuff and i never have on option to opt out in civil industry and or business.
Once again people, think just think , if good aliens cant provide to us technology, then this means:
1. They don't want to change anything!
2. They afraid of what we do , when we start to recover our memory of past life on alien worlds, maybe some of us done bad stuff, or even worse sent here by accident or even as spies, who knows what some people have done in past lives.
3. They are not sure, that they can defeat bad aliens, even with all theirs capabilities , they seem afraid
4. They unwilling to share any proof of theirs claims, those Harvey aliens, he could be in semitransparent form which can be recorded by camera, but they afraid of consequences.
