Little Snitch is literally used for blocking ads as well as other network traffic. My main point was that you don’t have to use it for blocking the other traffic, because Linux systems won’t have unwanted traffic to begin with, since you have full control over it. And for the ad part, there’s better solutions than network-level filtering if you have control over your browser.
So is it more that you don’t know what I’m talking about or that you don’t want to, for whatever reason?
These days OpenRC even has user-services. And writing a simple OpenRC service file is barely more complex than a systemd unit file, maybe even simpler, because it’s readable bash, not some declarative DSL.
Obviously there is in no way feature parity between those two, that’s the point, personally the one thing I’d like to have is something similar to systemd’s timers (which I actually prefer to old-school cron) built into OpenRC, but most other things I can live without.
