What have we contributed to the IT industry?

When I saw the Lua language today, I felt that I was not happy with it. I think there are also a lot of good IT companies and a lot of excellent IT people in China. But what have our companies and elites contributed to it? I don't seem to have heard of anything famous! Brazilians have contributed to the world's great Lua language. Russians have contributed to the world's rapid growth of the server. Americans have contributed less to Google's V8 and many other advanced projects, finland contributed liunx, a great operating system ..... But what have we contributed and what have we done? 360, sogou and so on many large companies are holding others' things to build their own things. Even with development, they are also hidden, hidden, and eventually turned into their own things, what have contributed to the technological development of the whole industry ......

I was wondering if Chinese people lack the spirit of sharing? Why? Who knows .......
