Which is exactly what improves and helps grow the open-source world?

GPL makes a product's code, and by infection/extension, other people's code, to be all released under a GPL license. GPL guarantees that users of open-source code won't act as leeches and will themselves contribute more open-source code. Isn't the act of choosing that license, in itself, "a huge commitment" to open-source?

Then they say: OK, seems you want to keep your code private, in order to preserve your IP and leverage over other competitors, and protect your lucrative interests... well that's fine too! You don't want our open-source license forcing you to contribute your code? Fine, we'll waive that requirement. Just pay up.
