On the Caveat Emptor (“Let the buyer beware”) side of things, I look at other metrics well before I rely on stars.
How many contributors does it have? How many active forks? How many pull requests? How many issues are open and how many get solved and how often and how lively are the discussions? When was the last merge? How active is the maintainer?
Stars might as well be facebook likes imo: when used as intended, they didn’t say much more than “this is what the majority of people like” (surprise, I’m on lemmy bc I have other priorities than what’s popular), now they mean nothing at all.
The biggest issue I see is that most of the tech is someone’s IP. If it’s not patented, it’s copyrighted or trademarked. Otherwise, it should be a doable PoC with old parts and a barebones firmware. I don’t need my FOSS printer to contend with Xerox, I just need it to poop out a page when I hit print.
I’d also love to see a FOSS page description language that could dethrone Adobe’s PostScript and HP’s PCL as the standards.
