Where I live the water is very hard, poor quality (but inside of the allowed limits), and also the pipes in my flat’s building are fucking old, so yes, I only drink from bottled or filtered water.
It might not pose a real risk, but I prefer err on the safe side. Additionally the Brita filter removes the nasty taste that the tap water has here and the kettle doesn’t have lime stains.
Not necessarily compromised, I saw a VPN provider (don’t remember the name) that offered a free tier where the client accepts being used for this.
And I suspect that in the future some VPN companies will be exposed doing the same but with their paid customers.
