I find it unlikely that such copy protection would actually convert a non-paying user into a customer.
I also don't want to make the software network dependent in any way.
Companies participating in that transformation don't get my money and I'm glad to know that this isn't one of them.
As a user of Monodraw in an airgapped environment: thank you!
I used to think that but then kept tripping across customers who ran multiple copies of my software after purchasing a single license. I now wish I'd tightened the DRM from the start.
Fighting piracy is generally not worth it. Those people would never pay, so you're fighting to stop a pirate from using it, not to get them to pay. There's a big difference.
