All the drive-by installs bundled into freeware/floss installers is enough proof that people don't read... I had to stop my mom mid-install after she clicked next pretty quickly, back before she had a chromebook... It was only chance that I was there with her... She almost installed 3 drive-bys with the one app she actually wanted... until switching one of my grandmothers to a chromebook, I'd have to remotely clean all the crap off her PC remotely twice a year... that wasn't at all fun.

I entirely believe there's a lot of people that just click on everything that comes up.
