If this is okay, I think, great!
Apple used to be against that, but I know there’s been discussion about consumer control over software (and jailbreaking).
Just be careful. If it is illegal, Apple may not go after individual consumers, but a business that makes money is something different.
Regardless, thanks for sharing! There’s a lot of great software on Macs that are in many ways more affordable and feature-rich alternatives to Adobe products. Adobe is still the leader, but with companies like Serif, their days may be limited.
