A perspective which may not have been considered yet is exactly what kind of value is being created in these open source projects: namely, value which is easily captured by SaaS startups. Is it really surprising that that <insert javascript library> is used by <insert techbro startup> to make <insert obscene valuation> without giving anything back? End-user open source software doesn't face this problem as often and I would wager is a lot more important for creating an open source ecosystem which serves people rather than serving techbro startups. I'm not saying that libraries are unimportant, but rather that there's not a lot of use-cases for JavaScript layout library #1,480 other than making some web app for some techbro startup, which is pretty far removed from anything useful to end-source. If you write projects which enslave yourself to techbro startups, don't be surprised when you end up enslaved by techbro startups.
