"Information" is a noun, hence it is a "thing".

Furthermore, the 'physical damage' it can inflict is the destruction or manipulation of physical memory cell states.

If you want to have the argument that a "thing" can mean "information" I wish you all the luck in getting a partner that agrees with you. Personally it's both for me, depending on the occasion.

There is no argument, "information" is a "thing", by definition.
