Definitely agree. I like the idea of it, but when I installed it for the first time and rebooted, it fired off so many confirmation requests for various cryptic services I had no idea what they were, I removed it just as soon as I'd managed to click through them all.
Little Snitch is noisy AF for the first day or so, but that's also kind of the point, right? You're running it because you want to know which apps are doing what. Those first sessions are enlightening. Wow, my laptop talks to all the things! That drops very quickly, though, as you tell it "yes, allow Slack to connect to" and "no, don't let Safari talk to sketchy.ru:8765".
I still get the occasional popup, but now they're limited almost exclusively to newly installed apps that I'm running for the first time. That's still an eye-opener: no, I don't see a need for a calculator to connect to Google Analytics. Deny!
Except for gamed, of course. There's no rhyme nor reason to which hosts and ports it wants to talk to. If you ever want to hack a Mac running Little Snitch, call your process "gamed" and the own will allow it through (if they haven't already set "allow connections to any host and port because alert fatigue lol").
It definitely takes some time, effort, and research to get past this initial phase. In the future, I hope they explore more automation / semi-automation around system processes.
