A bait and switch is an intentful swindle. I don't believe this is the case for most OSS. Many of these companies (e.g. Sun) had the greatest intentions, however at some point the purpose of a company is to make money. Some (like Automattic) are lucky enough to do this through hosting and/or a marketplace, but for most it will be some form of open/closed model or lock-in. Whenever I see a company whose product is OSS take on investor money, to me that is a red flag for the longevity of that OSS software.
