Linux is free. Do you mean to imply that Linux is nothing more than an advertising/tracking platform? I pay for cable TV, so I guess I'm not the product there right? Oh wait, even though I pay the real money comes from being able to direct my eyeballs at ads. The world is not that simple, and I keep seeing people parrot this exact line at everything. It is applicable in some cases and not in others, so don't whip it to death.

Windows is not gratis and has tracking.
GNU is gratis and has no tracking.
