Yes and no. People become professionals using tools that they're familiar with. 600$ a year for an industry standard that makes a person productive isn't a lot. But what happens when 50% of your workforce is using a different tool that they're more comfortable with because they've already invested 5-10 years into learning it? It's not expensive for a productivity boost once you're a professional. The question is, if you are a professional, and you're just now getting to the point where you can afford to start using Adobe tools, are they so much better than the tools you've been using your entire life that they're still worth $600 a month? Will they still provide a productivity boost that justifies their cost if they're not an industry standard anymore? Right now, Adobe products are still at least arguably (if not obviously) an industry standard. But when we talk about a market decline, a current decline in hobbyist usage may signal a heavy future decline in the professional market. It's not necessarily the case that they're completely separate from each other.
