The fundamental problem with increasing prices is that you create an opportunity for competitors.

If Photoshop would cost 5€ a month, then everyone would buy it because it is the best.

If Photoshop costs 50€ a month, they make more money, but they are leaving a huge opportunity for competitors to make a 5€ a month product.

I actually think the latter is better for the ecosystem. There's going to be multiple products, with Adobe at the top, but also a lot of apps from smaller developers. On the Mac there are for example Acorn, Pixelmator, Affinity Photo -- none of them are a full replacement for Photoshop, but they are decent options for people who just need to edit a photo.

Back when pirate Photoshop copies were ubiquitous, there just weren't any opportunities for smaller developers like there are now.
