Apparently they've been scraping Apple's network location database and plan to offer a substitute service running on GrapheneOS servers, as well as a way to upload data you collect on your device.
I worked on this a while back in parallel. You can dump Apple's entire database in ~2 weeks. Around 3 billion records including China.
You can compress it down to only a few gigs and have everything offline. I also got a ichnaea proxy though not as well tested. Been using it myself and it's alright,

I did look. There is:
- Location Services
- Secure User Plane Location
- Predicted Satellite Data Service
It's not immediately obvious what I need to enable in order to get better location services, if it's already enabled, and whether the feature in the linked post even helps with the issue. Why are you so hostile?
I use Graphene for privacy without a massive hassle, I don't care enough about my phone ecperience to be really into it, I just want provacy. And generally GrapheneOS has been GREAT for this.
Not all are, of course. Hopefully it's a minority. However, in my experience it is a factor that many less-technical people are ungrateful and rude even if I spend hours giving them free tech support. I suppose because they expect niche privacy tech to 'just work' more easily. After experiencing that hundreds of times it can become difficult to not become jaded.
