The comparison between those photobook websites and Affinity Publisher is what you came up with in your initial post. People are just picking up on it. So, to be clear: What you're saying is that Adobe InDesign is as easy to use as, say, Pixum? Or Blurb? I very much doubt so, and I think that comparison is unfair towards both InDesign and Publisher. Put an inexperienced user in front of an empty InDesign page and see how far they can get. I've done it sometimes, just as an experiment, at the beginning of InDesign courses at university. The overall result is that people are just completely lost if you deny them any guidance. The same is probably true for Affinity Publisher. But I think what's happening here is that you confuse intuitiveness with the fact that you just know how to use the software.
