I lost respect for them when they began blatantly duplicating the hard work and ingenuity of indie developers just to make a few extra bucks. Why bother thinking when someone else has done it for them?

I uninstalled all Zynga games and blocked all FB entries as soon as I found out this was a common pattern for them. I also shared that knowledge with my largely non-techie social network so they could see the kind of company they were supporting.
