I wonder if OSS world needs kind of Spotify/Netflix platform for OSS distribution. If I would put in analogy OSS Developers to Music authors and songs/albums to OSS projects then such distribution platform would be paying developers depending on how much their project is used and maybe some other criteria and everybody who would like to use some OSS would need to pay monthly subscription to that platform.
Thats true. But I guess for big project there was a reason to choose some framework. Usually with big projects without any framework you would end up with your own custom framework anyway to speed up development and it would cause onboarding new team members would be harder. But sometimes this is also necessary, look at FB, they built React because they needed it and later it was adopted by community and other companies. Its realy just about what your project needs. Btw. with backend development its same or maybe worse. There are as many languages and frameworks for backend development as stars on the sky :D.
I don't understand these kind of posts that 10 years back was frontend development easier. What is stopping people to use HTML, CSS, vanilla JS, or with jQuery these days? Nobody is forcing us to use React, TS on every project we do. Feel free to use jQuery if you think its the best tool for your project. All these technologies are just tools and you decide what tool you choose to get work done ;).
