Someone should do a write up for pihole vs adguard vs technitium vs eBlockerOS
https://eblocker.org/en/ (German product?) (BTW you're all welcome that I showed you a new thing)
Edit May 7: eBlockerOS seems geared towards better packet* inspection, hidden trackers protection, and fingerprinting. You can install a HTTPS cert* on your current machine so it does MITM packet inspection where it can scan*, inspect, and reencrypt from the looks of it.
Im probably going to run this at work on my test environment to see how well it does overall. Maybe less granular control, but I like is more* than just an adblocker like pihole.
