The point is that it wasn't developed by VC money. It was
bought with VC money after the fact.
It wasn't a "demo" for a paid product funded by corporate dollars or VC funding, it was just a thing that someone created, and released as an open source project.
It's hilarious that you think the companies dropping open source licenses for the products they bought are going to stop the industry using open source. As I said originally, it's going to have the opposite affect: it's going to make the industry embrace the very nature of open source and create forks of projects, the moment there's a sniff of a corporate buy out, specifically because of this type of activity.
