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.
When did I do both? Please quote or link the exact messages as evidence.
You also keep associating the term “evangelical” with me, without citing any evidence.
Also, your privacy example isn’t quite the same here, since you absolutely can have privacy with Windows - just block all Microsoft domains, use a decent firewall/PiHole/adblock/DNS etc. Or just soft air-gap Windows, allowing only selective traffic to pass thru a manually-configured per-app proxy gateway.
On the other hand, someone asking for FOSS apps and claiming they prefer FOSS, whilst still using Windows, is ironic.
