"Addictive" vs. "Addicting"

I've noticed that many dictionaries, against what I consider "better judgment", are starting to include common mispronunciations and newly made-up words as being correct. I wonder if perhaps the dictionaries are including "addicting" now because people so often use it, not because it's correct. I can see how it would be correct if the context were to go as follows: Joe Schmoe Coffee wants to make sure they have a large percentage of drinkers. They put special chemicals in their products which end up addicting the drinkers to their coffee. I don't see how "addicting" works unless it is followed by "whom" the thing is addicting. Addicting would have to be a verb, not an adjective or a participle adjective.
Some may argue that "annoying" can be used as a participle adjective, so "addicting" should be allowable in that sense. In case you haven't noticed, there are always strange exceptions to the rules in the English language. Notice, though, that "annoying" is also a verb.
