I am also sad to hear what happened. I whole heartily agree with @mvanroon, businesses don’t have much time to form relations to “inner circle” that might or might not respond - much less to search for right needle from the haystack to communicate with. This should be something that NEM foundation addresses rather quickly or it will see similar opportunities go by…
Yes yes, core devs are busy with Catapult, others are engaged with something else. I’ve read some people around NEM offer help for something but I suspect they are dealt with silence due to great pressure from providing Catapult which provides whole new playing ground and solves plenty of things. There are probably plenty of other reasons.
BUT… even if technology would be superb and best in the world it can be forgotten into oblivion without real use (tech sector provides myriad of examples from this) and inferior tech got the best of it because it was engaging companies/people. I sincerely hope that this is not the case on NEM technologies. Simple analogy: Linux is/was far more advanced from technical standpoint than Windows BUT companies have chosen Windows because they are getting service and attention. (Please lets not go into Linux/Windows flamewars, lets just take this as it is, analogy)
Edit:
This thread points out similar concerns than I have.
