There are a lot of poor quality open source packages in use. Some are just chaotic. But people still use them, often just keeping themselves much busier than they need to be. Of course there are a lot of high quality packages in use as well. So popularity does not correlate with quality (in many fields) If Wolfram open source their stuff and people use it, it won't necessarily be a vindication. At the moment they have people who are willing to part with cash to get what they make. That's a definite vindication for anyone who makes things.
