I agree with your sentiment here. imo they chose the wrong words to describe what they meant e.g. ~0.5-1GB memory usage is more like a hobby-setup (assuming you run it on the same hw as the services you monitor).
However, after scrolling through the GitHub page, I feel like this is not a service which aims at people (might be completely mistaken) who either have a small set of services to monitor (and/or understand the logs and/or the interest to do it) or have their homelab at a relatively low financial priority (1x 8GB 2400 CL17 is €15 here).
8GB for a single service in a (home) environment is, imo, still a lot, but I think it is a sort-of reasonable figure for what it does and need to do to make that happen
