Patchou. Your sponsor was quite accurate. People = Selfish pigs.
Alot of the money your getting off the sponsor program is off people too silly/ignorant/lazy to read what they're getting themselves into and in all honesty they deserve it.
Anyone using the program
should donate, shop or use the sponsor program.
90% of people wont do the first two and 90% of the people that do the latter do so in error, but you've got to make a living so you can eat and drink and pay the electricity bill. So I say leave it as it is or make it compulsory (If you make it Compulsory then you'll have to remove the Hide-Ad feature of the hypocrasy would be too great.)
If I was doing it i'd make 2 versions of Plus, one of which had more sounds, more features, better features and a sponsor program compulsory, and one with lesser features but a sponsor program optional. Might boost the number of people who really wanted the sponsor program.
I hope I made some sense in this post I tend to go off on one and loose the plot.
