When Adobe went subscription model, they increase their profits multifold. Someone's paying for those profits. And that's their customers. Subscription model is not cheaper, otherwise they wouldn't have it. They use subscription models to maximize their profits, and a lot of other companies have jumped on the same bandwagon.
Nothing wrong with a corporation increasing its revenue, decreasing costs and thereby improving profit margin. That's kinda what business is all about - isn't it?
The subscription model improves revenue by eliminating piracy.
It reduces distribution costs and and eliminates warranty costs resulting in a concomitant reduction in the producer's cost.
The small monthly subscription fee changes the customers' burden from a large, upfront capital outlay to a small monthly expense while also greatly reducing the customer risk associated with purchase - both of which might increase the number of customers willing and able to buy/use the product - increasing sales.
Undoubtedly, there are/were also, external market factors that might also have increased the company's sales - for example, an increase in YouTube content creators during the period.
These factors would all tend to improve profit margin - would they not?
I don't understand the outrage. The company is providing a product at at price. Lots of folks apparently see it as a good value and are happy to subscribe and enjoy the quality and utility of the product.
If you don't think it is a good value, don't subscribe. Use something else, make your own software package, whatever but don't bitch about the company being successful...just vote with your wallet. The rest will take care of itself (the invisible hand of the market and all of that).
