it's a lost cause. the people who want to pirate it will always find a way to circumvent efforts against it. better to spend efforts for people who pay than people who dont pay. better features for those who pay, instead of obfuscation for those who cant pay.
this is also good for those who cant pay, some of them are students or professionals who just simply dont have the budget yet.
you can also just pay for 12 months (sometimes it comes with some discount) or just pay month by month during last 12 months and you will have the perpetual fallback license after that which lasts forever (though you won't get updates until you start monthly payments again)
