Is that not a trivial amount for hands off DNS recursion services? Consider the cost to purchase a Raspberry Pi, set it up, electricity, wear and tear on flash storage, etc
If you point me at a checkout page for $2/month to not even have to think about plugging a Pi in, I’m going to pull my credit card out in a heartbeat. A single coffee costs me more. Think about your time!
Price-wise it'll probably be a no-brainer. Even though a pi can come as cheap as 2 or 3 coffees. A zero is sufficient for pi-hole.
But it's about taking control too. Personally I wouldn't like taking a service even if it were free, over hosting something myself, especially when it's made as easy as Pi-hole does.
Pi-hole is a tool to improve your privacy. Handing all your DNS requests to a 3rd party is the exact opposite. Now you have to deal with their privacy policy, track whether that company got hacked or bought etc.
Installing and maintaining pi-hole takes very little time.
