Indeed. 55% of all (not deleted) GitHub repositories are dead or archived. Frankly, I'm surprised the number is that low. I suspect it would be a bigger percentage if we somehow knew how many projects were simply deleted.
Here's a fun read, if you're so inclined:
Survival Rate of GitHub Projects - An Empirical Study - Livable Software
What's the probability a GitHub project dies soon? Are some types of projects more likely to be abandoned? Why is this important and how can we try to prevent it? This work tries to shed some light on these topics.

That said, it sort of pains me that we have to point out that it needs to be properly maintained. (It should eventually have a history of being properly maintained, which is really an important thing to consider.)
