I don't know anything about AdGuard in particular, but the general category of "Adblocker that is a really a VPN that really just loads a DNS server to block ads" is really problematic as: - cause lots of weird networking issues (impacting perceived stability) - are often "Free" b/c they are swapping in their own ads and malware [1] - are just in general a poor way of loading a hosts/dns file that in many cases they don't even own (they're just pointing to a freely available one) 1 - https://www.cloudwards.net/worst-free-vpn/ https://www.cloudwards.net/worst-free-vpn/
