there should be some kind of notification system whenever something goes unmaintained. ive used unmaintained software for way too long before finding out theres some fork.
the finding out alternatives is the annoying part for me, you always have to be on some niche place online (eg lemmy) to discover them. that and ive used a lot of security sensitive abandonware i really wouldnt otherwise.
https://crates.io/search?q=neofetch brings up 21 versions to choose from (21 are actual neofetch clones). There is also a library to help you write even more of them.
