Perhaps they could benefit from splitting up the package some if they do it in a smart way. They get money from non supporters from ads. So if they make it so that the smaller supporter packages that you suggest dont remove the ads. That only comes from being a full supporter.
Tbh. Ads are probably the worst part about the game. As Wolph once wrote and was ridiculed for they are somewhat shady (meet your asian/african/mexican girl) and some totally kill my browser (you are the 1.000.000th visitor, really! you won an Ipad/whatever) - so I guess they might scare off some people too.
I cannot install adblock on my office computer due to no admin right, but if I could I would remove the ads. I'd probably pay a
small sum to have BB remove them for me.
