Steam Deck does not support BattlEye for GTA Online
Such a crappy way of wording it and trying to blame the steam deck when BattlEye has said that they have had linux and wine support long before the steam deck came out
Official Rockstar Community (RP) Servers will not require BattlEye to play. Community Server launchers will disable BattlEye as part of their launch processes.
What makes RP servers so special that they don’t need BattlEye?

BattlEye has provided native Linux and Mac support for a long time and we can announce that we will also support the upcoming Steam Deck (Proton). This will be done on an opt-in basis with game developers choosing whether they want to allow it or not.
2 accounts consistently reporting the same IP, location and user habits etc being linked is more absurd than nobody ever noticing excessive uploaded data from their phones? It is very easy to monitor the amount of uploaded and downloaded data on a device, lots of people would have noticed by now. The amount of storage, bandwidth and processing power that would be required to monitor the audio from hundreds of millions of android users globally 24/7 would make this the dumbest business decision ever when there are so many easier and efficient ways to track users.
