I see this argument a lot, but I'm not sure how it detracts from their continued development. Oracle funds many engineers working on OSS and, despite having CLAs in place, retain the permissive license for most of them. In some cases they've acquired closed source software and made it open source (e.g., JRockit stuff). They're a major contributor to OSS.
