This doesn’t have to be correct. If the game cannot resolve the ad URL it won’t get a stream of course you could implement a check for that but who tf is gonna do that. Right. Noone. You would have to build in the ads or use some other domains not on the blocklist to still give the user ads. And if it’s an online only game that displays ads you would have to resort to distributing them via your own domain but after all this is not likely to happen at all! So yeah. Could happen is just very very very unlikely
I’m pretty sure I know what I am talking about I manage my own homelab and know this kind of stuff. sure I am not an expert but I still have experience in it. But your argument that nearly “all” of them have is just wrong. There are exceptions of course however not all Devs practically target a group that have a network wide DNS blocker installed. The amount of users would probably be way less than 1%.
