I'm not supporting this view but it is what it is unfortunately.
VCs that invest based on stars do know something I guess or they are just bad investors.
IMO using projects based on start count is terrible engineering practice.
Surely a project's popularity is often related to its utility. A useful and popular project seems like exactly the kind of thing a VC might be interested in.
Hype helps raise funds, of course, and sells, of course.
But it doesn't necessarily lead to long-term sustainability of investments.
