I'm trying to understand what you're saying here. Making up some versions here, we have Redis the software product being developed under FOSS up to and including version 42.0. Now Redis Ltd. comes along and says, "we're taking the product private". It sounds like you're saying that whether we're talking about all versions up to and including v42 can be taken out of the public domain and can't be used by the very people who made contributions to that FOSS codebase, making a FOSS fork impossible. Is that right? It seems like various FOSS licenses should be preventing this...
