For example, SetCPU has 50k-250k downloads and has been there for months so I'm guessing it's closer to 250k. That's not even counting all the pirated copies, and I would be willing to bet setcpu is one of the most pirated apps out there. I'm fairly confident that most setcpu users have installed custom roms as well. That's why I used it as an example. So when they start releasing phones with signed/encrypted bootloaders, they're turning off quite a bit more people than they think, IMO. Will this change anytthing? No. But hundreds of thousands of users are hacking their phones, whch is a lot more than most think. I realize setcpu only requires root access and has nothing to do with the bootloader, but I would say most who had taken the steps to root their phones have at least played wit a custom rom.
