But you can trust some of them. You need to know which ones have a history of caring about privacy
All I see in the tech world is the companies that have been caught red-handed doing shady stuff and those that haven't yet.
You say you can trust some of them based on their history of caring: can you? What's their history of caring other than how long they've sworn to do the right thing and haven't been caught doing otherwise yet?
Like I said, tech companies don't resist the lure of big data money for very long these days. If you think any VPN provider isn't at least seriously considering monetizing the traffic you send them to make more money on you than the few dollars you throw their way every month for the VPN service, you're deluded. I would never trust a VPN with all my internet traffic. That's just too much of a risk.
