This issue also bugged me for a while. It is more of cultural issue, and older the research group is, the less likely it is for research software to be open, in my experience.
In the area of deep learning based simulations, one good example of an open software is netket. The researcher their is pretty active in terms of github/gitlab/huggingface ecosystem.
