[tag:metro] is ambiguous and has to go, or you'll keep getting questions accidentally tagged to it.

I would suggest to use [tag:metro-web] or [tag:metro-web-java] or [tag:metro-java] instead:

 - [tag:metro-web] makes the user more likely to read what it is, but accidental tags could still happen.

 - [tag:metro-web-java] is as verbose as it can gets, no way that you can misunderstand that.

 - [tag:metro-java] could work as well, since the `web` notion might not be necessary.

Don't add `framework` because it adds no value to the tag name.

So, here's the approach I would suggest:

 1. Contact the sponsor that he is sponsoring the wrong tag.

 2. Sort out [tag:metro] to only contain Java Metro-related questions, [tag:metro-ui] for the design language.

 3. Move all questions from [tag:metro] to [tag:metro-web-java] or [tag:metro-java].

 4. Call Trogdor using the awesome sign and ask him to burninate [tag:metro] (and blacklist it).

 5. *???*

 6. Profit! Everybody happy...

Here is an image explaining it all with tags, SE team, sponsor(s), freehand circles, unicorns and Trogdor:

*Any resemblance with real-life persons, drakes or unicorns is purely coincidentally...*
