Its not freeware, its buyware with a really really dumb way of asking for payment.

well there probably are cr*cks and stuff out there anyway so what's the point of locking it after x days

It doesn't lock.

After 40 days, if you actually choose to open up the primary WinRAR application, a 2 second nag screen pops up.

Just have to click "Cancel".

Sure, it's annoying, but by no means does it restrict use of WinRAR at all, especially since CC never even uses the main menu of winrar.

I know it doesn't lock,

I was saying what would be the point in locking it. (except most of the general public don't do wa*es)
