I currently use TinyWall Firewall, it works very well, it’s small/portable, no complaints I even donated to the Dev but I would really prefer open source, also it needs to be user friendly like TinyWall so my non-tech family members can/will use it like they do with TinyWall.
Look. You can’t have it both ways. You can either be the “i use arch (and so should everybody else) btw” guy or you can be dumbfounded by people accusing you of being the “i use arch (and so should everybody else) btw” guy. If you do both (in succession I guess) you’re just a parody of your own pro-FOSS message.
I know I’m probably opening another can of worms by saying this but I’m an absolute privacy advocate. And guess what? I use multiple Windows-installations as part of my day-to-day. Yes I do want that number to migrate towards zero but so far, especially when it comes to laptops (and more so laptops with multiple GPUs) I just never saw any appeal in crippling my own experience just for the sake of subjective “freedom”.
So now imagine a person like me trying to look for help setting up a Pi-hole installation for the sake of privacy. In comes the evangelical “If you actually truly care about your privacy, why are you using Windows?” Sound familiar? How about helpful (in terms of getting someone closer to a Pi-hole installation)?
