No, it's an entirely separate new product they introduced back in 2015 [1], Little Snitch is still far and away their main and most important offering. Micro Snitch does fit in with their overall company focus of monitoring application background transmissions of your data, but it's a lot more minimal in focus (and in turn very cheap). I'm not sure why it's getting an HN post now, it hasn't recently received any significant upgrades beyond some basic Mojave compatibility/Dark Mode. Actually Mojave introduced some significant new per-application protections and permission requirements for privacy related equipment, including camera and microphone [2], so I'm not sure it's as relevant now as it was at launch. I suppose that even if you grant something permission it could still be useful to have more active monitoring of usage as well, it might get compromised or look legit but then do things you don't expect. ---- 1: https://blog.obdev.at/introducing-micro-snitch/ https://blog.obdev.at/introducing-micro-snitch/ 2: This can actually "break" old software in some cases, because it'll try to access something and fail but the OS permission dialog will be hidden by some other window or not show up properly. Sometimes you can work around this manually in the Privacy pane of the Security & Privacy preference panel, where it'll list software that recently tried to access a resource but couldn't and you can check it off to allow it in the future.
