I disagree - especially regarding Denuvo being good for anyone.
I think the most important justification for Image-Line to continue using the current regcode-based copy protection is that:
Non-intrusive copy protection with possibility for perpetual offline activation is fair towards legitimate, paying customers.
In comparison, Denuvo and other comparable copy protection schemes treat the customer as a thief by default. Personally, I would not want Image-Line to accept "treating paying customers as thieves" into their company values.
