I only use photo editing and publishing software for casual use. It's not my livelihood but it's just a hobby. As I was watching this one--economics talks about substitutes. In economics, we talk of substitutes as:
A substitute, or substitutable good, in economics and consumer theory refers to a product or service that consumers see as essentially the same or similar-enough to another product. Put simply, a substitute is a good that can be used in place of another.
Substitutes play an important part in the marketplace and are considered a benefit for consumers. They provide more choices for consumers, who are then better able to satisfy their needs. Bills of materials often include alternate parts that can replace the standard part if it's destroyed.
As I was watching it, I couldn't help but say that Adobe's policy (read here) might encourage piracy further. I bought the Affinity license at nearly PHP 4,000.00. The only recent complaint I might have of Affinity Photo is the lack of capacity to produce animated GIFs. Hopefully, it will become a reasonable plugin for animated GIF makers.
