screenshot of text: The material does not say how Penlink obtains the smartphone location data in the first place. But surveillance companies and data brokers broadly gather it in two different ways. The first is from small bundles of code included in ordinary apps called software development kits, or SDKs. SDK owners then pay the app developers, who might make things like weather or prayer apps, for their users’ location data. The second is through real-time bidding, or RTB. This is where companies in the online advertising industry place near instantaneous bids to get their advert in front of a certain demographic. A side effect is that companies can obtain data about peoples’ individual devices, including their GPS coordinates. Spy firms have sourced this sort of RTB information from hugely popular smartphone apps.

Is the baseband isolated?

Yes, the baseband is isolated on all of the officially supported devices.

And

The mobile Atheros Wi-Fi driver/firmware is primarily a SoftMAC implementation with the vast majority of the complexity in the driver rather than the firmware. The fully functional driver is massive and the firmware is quite small.
