I'm getting tired of these publicity stunts. Developers who knowingly try to pull a fast one should have all their apps pulled and their developer license suspended for a year. It's just too easy to leverage the review process to game the media.
I suspect the buzz they are gaining overlaps highly with people who have already been exposed to to taptaptap. This buzz isn't going to reach Grandma and cause her to buy that "rebellious software from that tappy place". Meanwhile, their app is no longer earning them money and Apple is going to be keeping a watchful eye on all of their subsequent releases.
Not to mention, the decay on this type of buzz probably has a half-life of 12 hours after it reaches its peak in one or two days. In two weeks nobody will think much of this story, and I doubt they'll have released anything to take advantage of the buzz.
Now, their buzz about earning $500k+ on the app, that was pretty helpful. Nothing sells a product more than press about how people can't get enough of it. Just ask Apple about that one.
There's a reason that Android outsold Apple last quarter, and it wasn't antennagate.
