I think downloading one today is fine as well. It's possible that it's going byo get worse in the future, but it's not like Wikipedia was perfectly "clean" and without its flaws/bias before January 2025. Wikimedia looks like they're going to offer so e nominal resistance to whatever tf this is, but we will see how it plays out.
Question (that I'm not going to look up), but does wiki have a way to download everything with the change history? Cause in that case you could have an offline copy that you could roll back as far as you'd like.
