MACMAN If I recall correctly, there remains strong demand for some forms of OS 9 functionality to be moved over to X. That includes a nice, simple interface. This app adds functionality over the built-in firewall, but is not MEANT to be a Brickhouse or NetBarrier. It says what it does, and does what it says -- very well.
If you're a Unix Geek who prefers an interface which hasn't (if you'll recall, DiskWarrior performs some highly-complex functions, yet maintains an elegant, simple interface) been well thought out, be my guest and go for it. Brickhouse is certainly more configurable, and has its digital demographic. DoorStop is similar in that regard. Brickhouse, despite its functionality, could use a major facelift. DoorStop beats it hands-down in that department.
So, in short, your criticism really doesn't apply, as the target audience/market is not the same.
