Projects vs. products. There are commercial open source-based products (e.g. from Red Hat that I used to work for) that have the same sort of support that other enterprise software products have. And there are the upstream projects (that Red Hat contributes to and interacts with). There is no expectation about contributing to open source products other than paying money to a commercial provider. There are a variety of reasons why you may benefit from them being open source-based but they don't come with any particular expectation of contributing upstream directly as a user.
