Then don't buy it. Not everything in the world needs to be made free just for you.
Free and open source is important and it's perfectly fine to be critical here.
I agree that I would never pay a subscription fee for any kind of system functionality, but there is a lifetime purchase option available, so there is no grounds to critique that here. Having extra payments models available in addition to a regular purchase model does not make a product worse.
They can log my keys all they want, I would never give a program like this internet access because it has no valid reason to ever connect to the internet (after purchasing a lifetime license). If you're serious about your privacy surely you take a little bit of responsibility for not giving every program you run unfettered access to your system?
