No idea how this would play into any Apple lawsuit.. but anyway..
Yes, you can disable both widgets and camera from the 4.2 Lockscreen, there's an API for it, and the app below lets you do just that:
It does not let you change the lockscreen etc.. It simply doesn't let you enter the camera directly (swiping to the left from the rightmost screen) or add any lockscreens. You can select either or both options (camera/lockscreen widgets) And it might limit you to the single Clock lockscreen if you've added more, not sure.
Things like music lockscreens etc still work. It more or less makes it like the old lockscreen in function.
