While it is certainly now quicker and cheaper to do this, it is not clear that maintaining a copycat app as an ongoing concern has much more business value than it ever has. Take Photoshop. Pixelmator existed (acquired by Apple eventually). Photopea is still independent. What else... Sketch? Figma and Canva for the "unicorn startup" category. Procreate serving a different chunk of users. Is there room for many more new entrants in this category to gain significant marketshare? Is the ability to dupe Photoshop the actual blocker?
