Pine64 boards rarely need proprietary software and they don't need it to boot like the raspberry pi does. However, that is a discussion for another time.

You are also illustrating my point. The Graphene community has a my way or the highway mentality. As it turns out stock will often be more secure as it will have the latest security updates and will have less people handing it in general so less risk of supply chain attack from a bad actor in the community. However, this is a non issue. I find a lot of the so called security holes to be fairly mild as they require very specific targeting to exploit.

In general, the people around Graphene os and Divest OS are very toxic. In the F-droid board meeting the issue was brought up that the is censorship is promotion happing for Divest OS. People who criticized Divest OS were getting banned. The person who brought this complaint has a page where they go over there beliefs and bring forward evidence. I think they are a bit harsh but they do have a point.
