I agree. One of the challenges is that in many countries the Government seeks to control what resources teachers can use, rather than trust them to choose their own.
I encountered this issue once when a TESSA colleague arranged for Olivier and I to attend a meeting at the Ministry of Education in her country. I suggested that I show the officials some videos I had of teachers using TESSA materials in school. But I was asked not to as TESSA OER have not been officially approved and my colleague was worried the teachers would get into trouble - even though the videos showed active learning in action!.
