Not only that, but if the trial works that way, you can repeat it any time you need to record something. The app probably dropped a prefs file somewhere (the old-style Mac XML preferences files), delete that and go again.
I'm often saddened by all the normalization of all the things people do to cheat their way through life. Why does everything need to be physically prevented just so people don't find a loophole to exploit? And then just act like it's nothing or are even proud of it? There is a trial period + you are asked to pay if you keep using it after? Well, pay up if you do. You also (hopefully) don't steal candy from the supermarket, even though it's "actually easier than just paying". Why would it be any different for software?
This would actually be easier than just paying.
