Term for Negative Promotion
What is the term for speaking well of an object, by identifying the negative attributes it has. ie 'Product A is non-poisonous, odor-free and not expensive'. 'Bill does not smoke or gamble'
Solution 1:
The closest to that definition that I see is actually a pair of phrases, not a term:
'...damning with faint praise'
or
'...backhanded compliment'
Each is used as a way to infer that there's nothing good to be said; a form of criticism.
