There may be a signal-to-noise problem, but the amount of useful open source projects and the extent to which we rely upon them has only increased in the past 20 years. “Open source” includes projects like Go and NodeJS, which are hardly trivial, disposable projects like you’re referring to. Pretty much all crypto is open source and people have invested tens of billions in that ecosystem. I could continue and list at least half a dozen projects that are considered critical infrastructure which are developed in that fashion.
