[Cthulhu_]

I don't speak legalese, but does the absence of a termination clause mean it cannot be terminated, or does the presence of a non-terminable clause mean it cannot be terminated?

That is, if it's not explicitly mentioned, which one applies?

There is a termination clause which lists the acceptable reason as being a failure to fix a breach of the license within 30 days of being notified of that breach.

The fact that there is no "we have a new version" clause listed in the termination section would likely go against wizards but they are likely to claim deauthorization is different to termination.
