I'm curious about what exactly you mean by these two sentences. Particularly the second one.
Is this circle you speak of the one where a company announces an open source product and once the goodwill—that open source development gives it—ensures a number of contributors and early adopters, helping the project grow until the company thinks it's good enough to monetize, at such point they close it down and start charging everyone; then they start a new open source product with the extra money, rinse and repeat?
