"We like to brag about how the games industry brings in more money than the film industry, but as soon as someone like Zynga makes enough money to trigger our envy, we invent interpretations of the game rules to say it’s not okay."
I seriously doubt that the criticism against Zynga were due to game developers being envious of Zynga. Frankly, this is a straw man and avoids the valid concerns people have about games and their addictiveness. It's not about rules that have been broken, but what responsibilities game developers have.
"Meanwhile, we are breaking the very same rules: the addictive qualities of Facebook social games can be found throughout all our games."
Maybe it's not a question about if games should have addictive qualities but rather how much and where you draw the line? Games can have a profound effect on a individual and affect their behavior and if the gaming industry doesn't routinely discuss the various ethical and psychological effects of gaming, they risk being seen as irresponsible or oblivious towards the well-being of gamers.
"Jane McGonigal bent the rules to bring her buddies up to share her rant time, but her shenanigans were sanctioned by the industry guard."
McGonigal was "sanctioned" because conferences, like most other IRL interactions, need order to function. Maybe the conference panelists were unnecessary strict and actually caused a loss by stopping McGonigal from talking, but many interactions would become difficult to participate in simply because people gamed them to their benefit.
