PUT BEFORE A COURT, NEITHER ADOBE NOR AUTODESK WOULD HAVE A VALID REASON FOR WHY, AFTER A CONSUMER HAS COVERED THE COST OF A PERPETUAL LICENCE, THEY SHOULD NOT BE GRANTED ONE.

Sure they would. For one thing, we agreed to the terms when we subscribed. For another, even if I subscribed for six years and paid for the full cost of Photoshop...it was the price for Photoshop 8 years ago. They could reasonably argue that Photoshop 2020 is more valuable than Photoshop was back when it was Photoshop CS, and I have not paid for that.
