Strongly disagree. For me, what's implicit is that any software, commercial or F/OSS, can be abandoned at any time - because that's just the way it is. A remedy would be to use software coded to a specification with mulitple implementations such that in case a project folds, you might be able to switch over to a different implementation. The Java EE ecosystem used to be like that until around 2012 or so.
