I haven't done a ton of research in this area, but I'd certainly like to use OpenWRT or OPNSense on my home routers/firewalls.
Side note: I've been trying to figure out a decent way to get rid of Android on my Galaxy S9+, but it appears to be locked.
At the end of the day, I just want to be in control of my bandwidth, my data, and know whats going on. Big companies are making this very complicated with all the tracking.
I recently re-enabled my pi-hole on a virtual machine, and it never ceases to amaze me what is talking to the internet without my permission. After digging into DoH a bit, I'm about to the point where I think I need to put in an outbound proxy, deny all outbound access except via the proxy, and iterate again and again.
I just don't want to have $200 a month in power bills to support my home network to save bandwidth and know what is traversing the net.
