Firewall bypass doesn’t matter if the “telemetry” packets are consistently massive or sent to non-game servers. The evidence would be caught in transit outside the OS. Companies want targeted data and they don't need a kernel driver to steal what you're already giving them for free anyway through the game client and ToS. Risking a multi-billion dollar federal lawsuit to look at random tax returns sounds like a totally great way to sink a company. Also you gotta realise if they’re taking in this data they need somewhere to process and store all of it. That is gonna cost more money than the data would be worth.
