The cause is not the issue, rather the presentation because the banner covers an important part of the screen for playing the game which is after all the primary reason most of us come here. I suspect most people here are in full agreement with the sentiments raised by the petition, I also suspect that many like myself don't like it interfering with playing the game.
If for example it was on the family page (the only place it isn't) instead of in the actual game play then everyone would still see it and it wouldn't impact on playing.
I for one couldn't care less with the sentiments. I personally don't trust people to all be inherently good. I find that most of the people who distrust the government in all things are deluding themselves into thinking that the average population is any better.
