Humans, in general, do not understand how non-interference works. On Earth this tends to be all or nothing. You tell your children that sex is nonexistent and punish them for thinking about it, and then one day they are married and can have at it - all or nothing. In between is a swamp that everyone is distressed about - teen age petting and extramarital affairs and the curiosity of youngsters. Theorems are taught at school as absolutes, even when they are being questioned at the highest levels.
Absolutes are so much more comfortable, and avoid all that unpleasant discussion.
In particular, they avoid that uncomfortable feeling that one really does not understand how things work. Non-interference does not constitute staying utterly away from emerging entities on 3rd Density worlds or avoiding certain subjects because they cannot be explained fully. This is a human concept, based on the way humans try to control their environment, but is not how the rest of the Universe works. In this they must wait until a human gives The Call, signaling an interest in having a conference. This orientation is notorious for not telling the truth, and no technology has been gained - none .
