Makes sense. We send everything through it by default and then we have a separate device group for non-Pihole DNS handling. Devices such as work computers that might get weird or have issues get put in this group. Everything else is by default put through Pihole until we have a reason otherwise.
I definitely commiserate with this. This is almost certainly the biggest moral quandary in my life. I think in my lifetime there will be a tipping point where vegetarianism will be a large enough minority to make it personally viable for me, but for the moment I reduce consumption where I can. Breakfast sausage will be the hardest thing to give up for me - but I continuously try meat alternatives in hopes of finding something I like.
