If a startup had snagged one of these domains and had built a community or SEO with it, could you imagine that being taken away from them without any sort of due process?
The sealed bit is weird, but bankruptcy judges are awfully sensitive to economic value. I'd be surprised if they would do something like that.
Of course, if the domain were seized in that case, due process would still be available. The startup's lawyer would immediately file with the judge in question asking for control to be temporarily restored to the startup while the legal stuff plays out.
