Positon (https://positon.xyz/) is a geolocation service closely tied to a group of people targeting our team with harassment. We urge people to avoid submitting their sensitive location data to this service. People involved in it have supported doxxing and swatting attacks.

They intend to lock people in to the service by keeping a lot of the data proprietary. They've repeatedly talked about locking people into it and avoiding having alternatives to it. Their priority is having control and ownership of data while sabotaging decentralized approaches.
Having an open source client/server won't make up for having proprietary data requiring giving your location to a server. They want to lock people into streaming their location to them in real time. Replacing Apple or Google with far less trustworthy people isn't progress at all.
We're going to be supporting and funding an approach where the data is available for anyone to use local databases on their devices or host their own servers. For GrapheneOS, we plan to provide both a local database option and a GrapheneOS server option. We'll only use open data.
Don't contribute your data to a service trying to centralize control, particularly one from the folks behind the astounding insecure /e/OS.

We've published an initial article about it:

It's exactly what shouldn't be happening with a successor to Mozilla's retired location service. These folks already used harassment and other underhanded tactics such as false reports to deter competition.

@GrapheneOS do you have a recommendation for a service like this that works on iOS as well? I'm trying to get my friends/family to switch from Life360
@tkk13909 You can't use a non-Apple network location service or local alternative on iOS.
@GrapheneOS Maybe you should check your claims about /e/OS before spreading false information and your usual FUD against /e/OS & Murena.
@GrapheneOS is there a particular reason why the edit on this post was made?
@navi It didn't end up being an open data service after all.
