lol. Why would someone want to sell a broken class/snippet that doesn't even work by itself? People out there do TONS of work just for open source projects.
nginx, Apache (and Apache's projects), hell just look at GitHub and all the projects on there. Laravel, Rails, Ruby, PHP... There are tons of open source projects that take more effort than you've lived productive days in your life.
If everyone thought like you, we'd be living in a different planet.
Instead, thank you:
https://github.com/google
https://github.com/Microsoft
https://github.com/apple
And hundreds of thousands of other individuals, businesses and everyone in between that contribute to society.
