Libraries are where the complexity should be. It it's used by 200 people, it makes sense to put the work in there, rather than duplicate it 200 times. Library developers obviously deserve nice things too, but that is why they should be getting paid for their work. If TypeScript is better for users(I think it is, although I would prefer we move the whole world to Dart natively with no compile step....), then it helps you make a better product. Which you should be getting paid for, as many FOSS devs are.
