Cellular carriers sell your real-time GPS location even if you turn off your phone (GPS chips operate outside the network)

They sell cell-tower data, not GPS data.

The article literally says "cell phone location data from nearby cell towers. It's less accurate than using GPS".

Generally, carriers only have access to the RAN metadata (cell sector, signal strength, etc), not GPS.

And in Europe they can't sell or pass on personal data. They can aggregate it, and sell aggregated data (e.g. for transport planning purposes)
