I used to disagree but not anymore. I think maybe the assumption is that you will be dissatisfied enough w the app to want to use another editor, and also that's easier to write Markdown than use the UI. Assuming good exporting facilities or lack of a proprietary format and quality UX, I'd much rather have the best possible editor than be able to write Markdown. It's much more important to e.g. add images, resize them, add sketches, graphs, and/or tables, or perhaps link multiple notes together. All of this is painful or impossible with Markdown (and editing Markdown on mobile is sucky). Markdown I think is an attempt to merge markup and content in a way that retains both, but it sucks for anything beyond simple header/paragraphs/lists.
