The problem with AGI research is that there have, to date, been few ways to survive as an AGI researcher. So once the commercial platforms became available to apply machine learning/AI whatever you want to call it, there was a way to continue Narrow AI research projects with the possible hope that maybe someday these narrow approaches would help lead to AGI.

In fact the whole AGI/HLAI/Strong AI thing has gotten a bad rap over and over that the majority of super serious researchers won't even talk about it in any seriousness a la Norvig et al. In fact Norvig arguably openly mocks AGI focused groups.

So until there is a real interest from some party that has money to put several billion into hardcore research, we will continue to see AI development live largely in the commercial world. Open source is a possibility like with opencog but history indicates that the bulk of the "big" minds and money don't go that way.
