If this is the company I think it is, then they took my last name as well. They're legitimately using it, even if you may not like the use. I got around it by using the .me extension instead. You can always pick one of those others instead of .com.
My best guess would be that's partially it. The other part being consumers are getter wiser when it comes to purchasing things. There's of flood of apps that lack polish and are quick cash-ins, and at this point the novelty of fart apps and what not has worn off.
