That's why intellectual property law exist. If I spent years writing a book and you were allowed to copy it and sell it then obviously you're going to "out compete" me by default. You didn't incur any costs in producing the thing you're selling, duh!
But other databases don't need it, and stayed truly open source, because their business model doesn't rely on being the only hosting provider.

Indeed, you gave it away for free, saying I could sell it... It doesn't take a business genius to know AWS can undercut your hosting services.
It goes to show that most of these companies don't really care about open source. They cared more about making money and open source was a useful facade to get people to contribute for free.
