Users of pirate IPTV services in Sweden are actively trying to circumvent new ISP blockades ordered by Stockholm's Patent and Market Court. The court sided with rightsholders Viaplay, TV4, and Discovery, requiring Telenor and other ISPs to block subscriber access to pirate IPTV providers. This triggered a cat and mouse game is likely to intensify the call for broader blocking measures.
I think PiHole is using Unbound behind the scenes. What I like about Blocky is not only does the performance to be much, much more solid using an upstream resolver with high latency (VPN exiting in another country), it automatically refreshes the denylists (something I think PiHole has to do in a more roundabout way).
