I mostly agree, but I've been blocking ads however ways I can for years now, and I'd say a few minutes of setup has saved me HOURS of dealing with ads at this point.
Plus... Building a PiHole was downright fun and easy.
I know this is late but I did a PiHole for years as well. But then I needed another solution for being out of the house, and my housemate later complained they wanted to see Facebook ads…
And like the other poster my gateway didn’t work with a a pihole so I had to change each clients’ DNS (which reverting for the housemate was a solution).
It was worth it but ultimately I needed more than just a pihole, sideloading my iPhone every week with custom YouTube apps, trying to find a custom twitch app to sideload, having to use Yewtu.be on mobile, etc. None of the apps like Adguard blocked ads in other apps well enough from what I experienced.
I wish I'd been able to get the pihole to work as easily as it sounded. It looked cool. But it was incompatible with the router from the ISP I had at the time, and rather than also buy and setup a new router, I just packed it away. Now I have a new ISP with a different router, and I'm sure it's incompatible too.
But at least it only takes 30 seconds to install ublock origin, and no extra hardware.
You should really consider getting a proper router like Unifi or the like.
It's a one time cost and it will save you from these issues no matter what ISP supplied crap you end up getting.
Just plug whatever ISP router directly into your own, more capable, router and your home network will look identical, no matter where you move to or how many times you change ISP.
That said, running Pi-hole on a Raspberry pi is a treat!
