My router just ate itself after the breaker on the house got cycled a few times in rapid succession. The router is almost a decade old, so perhaps it's not surprising. As a consequence, my pihole is temporarily out of commission. When we first set it up, we had IOT, android, chromebook, etc. Currently the whole household is on Linux and we just have a couple of smartphones. (plus a steamdeck) My wife has a few ugly apps (facebook, instagram, etc) but outside of that we're in much better shape network-wise.
I used to spend a lot of time on my pihole trying to "fight the internet," but with this recent breakage, it just feels like what I need to be doing is just visiting fewer websites, owning less connected tech, and doing other things such as working outside or reading books. Blocking javascript goes a long way, but just avoiding bad websites, web apps, etc seems to be the only long-term solution.
