Votes are not a measure of the on-topicness of a question on SE.
So to that end, it's not that odd at all. Those questions earned a significant number of votes early in the site's lifetime before the policies really settled down to the relatively-steady-state we have now. As time went on it became clear that despite being popular they were the kinds of broad and discussion oriented questions that are better asked elsewhere on the internet (on forums, or maintained on wikis).
You don't really seem to have suggested an alternative option or clear policy on how we might address the issue, other than "based on the viewers" which I presume means you're suggested that we use some arbitrary threshold of score to re-open a question regardless of the close reason? I don't see that as viable at all.
