I’m as paranoid as the next person but what’s the purpose of this article?
If you don’t like closed source software and don’t trust the developer(s), then don’t use the software. Why waste time writing an article that all it does is critize the developer’s decision?
If you care so much about the software you run in your computer, then do what I do: open a disassembler and reverse engineer the code, inspect every single HTTP(S) call, every network packet, every system call, and then maybe you will feel at ease.
When I click on the “Download / Buy Now” link [1], Safari tries to download it instead of visiting the page. I tried with cURL and discovered that the page is returning a “content-type: application/octet-stream” header, which makes no sense because the page is just HTML. Also, I can see some portions of raw PHP code in the HTTP response, so I think your web server is not interpreting PHP as it is supposed to and instead returning the raw content from the PHP file.
edit: In fact, every PHP file is being leaked, for example, this file [2] contains a $hash_salt , which is supposedly being used to “prevent[s] users guessing filenames and make data more secure”
last thing in the world i want is to install proprietary software on linux. even less so is something meant to be security software and interacting directly with my network stack.

To each their own, I guess, but that would be a hard pass from me. One example from mobile: FF on android keeps trying to connect to its various services (like firefox.settings.services.mozilla.net). For privacy reasons, I use NetGuard to block this and other similar domains. But there is a gotcha: there are sites (like seekingalpha.com) who refuse to load if access to these same domains is blocked - even on a completely different browser! With NetGuard I can still visit those sites in the secondary browser while blocking Mozilla tracking. With DNS blocking I wouldn't be able to do that.
NetGuard is a solid tool for Android, but managing a whole home lab is a different beast. I've got dozens of VMs and containers tucked away in Proxmox; if I tried to micro-manage per-app permissions for every single one of them, I’d never get anything else done.
I prefer to take the hit on those rare site-breaking edge cases if it means I have a single, transparent "source of truth" at the DNS level. It's definitely a trade-off, but I'd rather spend my time building things than perpetually tweaking firewall rules for every new service I spin up.

One nice thing about LittleSnitch on linux is that it comes with a web UI by default. Is there anything like that for headless systems using OpenSnitch?
I get the appeal; the Little Snitch UI is undeniably shiny. But for the headless Linux nodes in my Proxmox setup, I’ve never really felt the need for a proprietary dashboard just to see my network state. I’d much rather export my logs to something like Grafana or just check my AdGuard dashboard at the edge. It feels more "Linux" to keep the tools transparent and open than to invite a mystery binary onto my system just for the sake of a pretty graph.

I wrote GlowWorm ~20 years ago, duplicating much of the LittleSnitch functionality at the time.
I remember discovering remote kernel debugging across ethernet; it was magical.

The website is preserved for historical reasons. Nothing there has been active in a long, long time.
Glad you also talk about OpenSnitch. It is critical to have it installed.
OpenSnitch and PiHole are simply a must on every network.
for folks on the mac, Lulu has been a great option too. https://github.com/objective-see/LuLu
objective-see is carrying an immense weight for Mac users

Can you elaborate on ideal pairing?

How anyone could trust OpenSnitch is beyond me.
Please elaborate
