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.
This is Beehaw and we aim to be a nice place, right? So to me is kind of pointless this kind of discussions and I just meant to say that your comment sounded very judgemental and it could be written in a nicer way, that’s all.
Edit: Check OP’s new comment on the post.
