- the author of LuLu is a security researcher; he also wrote "The Art of Mac Malware"
- I already bought two versions of Little Snitch and wasn't willing to pay for the third one
- contacting their support left a bitter aftertaste
I have probably also paid for three versions. It’s a great piece of software and they do not require upgrades excessively.
But I will try LuLu. I would rather my security software was OSS.
