At this point to me, review bombed just means many people are unhappy with a product, likely for notable reasons. Any other connotation added would require me to trust the integrity of the journalist using the phrase, which is a bar they have almost universally decided doesn't matter, particularly when it comes to media journalism of any sort.
I feel it should only be used for when there's some agenda pushing going on (like the whole woke crying whenever the incels are triggered by something), not for legit reviews due to malpractice from the devs or publishers or whatever.
