The thing is that it's not really complicated anymore. It may be my area of expertise, but just following basic step-by-step instructions, it took me about 10 minutes to have a full ad-blocking, Wireguard VPN server on a DigitalOcean droplet by using Algo: https://github.com/trailofbits/algo , including the setup for my phone and iPad.

Algo is a great project and I also use it, but if you’re running it in production and not spending some time each month at least on security analysis and review, your self-assessd expertise may be more of the Dunning-Kruger variety.

I have had one up for around 2 years now and would say I have spent less than 5 minutes maintaining it over that time period. I did spend more than typical time setting it up because I added a custom php page so I could remotely add client ip addresses to the dns iptables whitelist, but I could have just done the basic setup in <20 minutes. It’s solid as a rock. Am I lazy about it? Sure. But I don’t quite consider it critical. It’s just personal use basic internet. And if something were to go wrong, most if not all client configurations have a backup/secondary dns option anyway so as long as that is configured things keep working fine, just with ads.
