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.
@GrapheneOS do you have a source for these doxxing, swatting, or lock in plans….?

@kali

We've posted about the harassment from Gael Duval and people who work for him before, so that's available. It also partly happened on Twitter and is still available there.

The source for their lock in plans is their private chat room for discussing coordination on making a proprietary location service and getting all open source projects to adopt it.
