I don’t think they need to for there to be value. Sure, maybe there’s spyware in free software that they haven’t found. But we know that these advertising companies are putting e-stalking code into all their products right now. Trading that certainty for an unknown is a net benefit.
Tracking typically works through fingerprinting. Using free software alone won't magically protect you against this, every website's a program with JavaScript on. Lots of free software is also multiplatform. You'll want to apply additional defensive measures, but you can apply those even on Windows, running Firefox or Chrome. Mind you, you'll then stand out for using those defensive measures.
I generally appreciate source code access and independent auditability, and I do have an appreciation for the intent. But the way people discuss these topics is downright embarrassing, which is what I was hoping to shake out of this. "Just install Linux bro, it's better than pussy bro. What, u still got dat spyin machine goin on?? [links a 30 minute Mutahar video with him faffing about with some technologically trivial bollocks he visibly barely understands]" Please. I think it's pretty agreeable at least that this about as far removed from well supported decision making as one can casually get to be.
Most people switching to Linux and free software alternatives in hopes of better privacy do so based on vibes, not on any rigorous research. And that's fine. Just wish they didn't pretend it wasn't the case.
