I think this gets at an insightful issue - In Flickr's heyday, much of its userbase was professional, aspiring, and amateur photographers who were effectively power users. They viewed Flickr as something like an extension of Lightroom, so they used it for storage but also curated their public profile, lists, etc in a sort of proto-Instagram way. When Flickr repositioned post Yahoo acquisition, it felt like it was aiming for more of a Google Photos-type use-case that was very passive and "it just works", which felt very different from how it had been popular before. I think history bears out that this was a poor decision, we don't really have major players now that glue those styles of usage together like Flickr did. I think it just required a higher level of effort in both the software and the users, and once Flickr pushed away the audience that enjoyed that level of effort to try to acquire a more set-and-forget audience it lost the first and failed to appeal much to the second. I think the old core Flickr userbase often went to 500px, which I don't like as much but is closer to Flickr in the good old days.
