I mean in regards to them being mostly trademarks of other companies.

You can use them for whatever you want. If you run into any legal trouble, just tell 'em shasta from the internet said you could use them.

There's plenty of fair use cases for the trademarks of others, you're pretty much free to use them as long as you are talking about the products and companies the trademarks belong to, and not trying to abuse them for my own products.

As for why you would want to use someone else's reproductions of these trademarks instead of the official images, I have no idea...

That entire set looks dangerous.
