I think this list is greatly erring on the side of caution. Some of the descriptions are incorrect, for example:

Aspirin (Bayers) is trademarked in several countries around the world, including Canada and the United States. The word Aspirin cannot appear on any imagery submitted to the RF collection.

Bayer famously lost its trademark for Aspirin in the United States after WWI as part of war reparations. It is still trademarked in Canada and many other countries, so possibly should be avoided in photos that are being used globally.
