One reason why Adobe continues to make a lot of money is that Photoshop and Illustrator files are like what Word and Excel files are in businesses and universities: currency. People trade these formats around, which makes them way more durable. But that durability can't make up for a more important aspect of some software — especially creative software — whether or not people love using it. Go to the Affinity forums and witness the fire in people's hearts. I imagine there was a time when people felt that way about Photoshop. It's not that I want Adobe to fail. I just want great software.
All I'm saying is: don't mistake Adobe's ability to make money as a sign of love for its products.
