Do we need the Adobe, Microsoft and Apple tags?

On Ask Ubuntu we have several companies represented as tags. There are [tag:adobe], [tag:microsoft] and [tag:apple]. I don't think these tags are useful, and perhaps they should be removed. We don't have experts on any of those companies, nor do they have something to do with with Ubuntu/Canonical. Yes they have products that run on Ubuntu, but those products already have their own tags:

[tag:microsoft-office]
[tag:adobe-acrobat]
[tag:itunes]
[tag:ipod]
etc.

I don't think we need tags that encapsulate all those products. And we don't have experts in the companies themself. I think these tags don't really have a use. Should they go?
