Developers are entitled to earn more money when they continue working. On the other hand, it is unfair how consumers have frequently needed to re-purchase products that they bought with the impression it would last a long time.

At least, the developer should specify how long the product will be supported for security and bug fixes.

A great solution, if you can pull it off: You continue maintaining the base product indefinitely, but "v2" features are disabled until the user pays more. And if you buy v2 in full you get the full feature set.

I don't really care about any of that. I just hate when a product is advertised as "one time purchase" when it actually isn't. I haven't got a single problem with developers charging for a new version, just be crystal clear about it.

users who bought a license of MonsterWriter version 1 three years ago are using the latest version today without any additional payment.

That's cool. What happens when version 2 comes out. It just says 'one time purchase' on the purchase page. One time purchase forever? Or one time purchase and then more times when the time is right to pay one time again?
