I was installing the Beta of Messenger Plus! and I noticed that at the beginning, it has a 'Beta Warning'. As soon as I saw that, I thought that it would be a great idea if something like that could happen when the sponsor program screen comes up, so people can't hammer the next button, choose some random option then keep hammering next. It would really force them to pay attention, and if they click ok to exit it by accident, chances are they'll read the sponsor program screen, and choose not to install it.
I personally think it would be great if it could be done
